The sound vibration [[waveforms]] are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a [[gramophone record|"record"]]. To recreate the sound, the surface is similarly rotated while a playback [[Record needle|stylus]] (or "needle") traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a [[diaphragm (acoustics)|diaphragm]] that produced sound waves coupled to the open air through a flaring [[Horn loudspeaker|horn]], or directly to the listener's ears through [[stethoscope]]-type earphones.

[[Alexander Graham Bell]]'s [[Volta Laboratory and Bureau|Volta Laboratory]] made several improvements in the 1880s and introduced the ''[[graphophone]]'', including the use of wax-coated cardboard cylinders and a cutting stylus that moved from side to side in a zigzag groove around the record. In the 1890s, [[Emile Berliner]] initiated the transition from [[phonograph cylinder]]s to [[phonograph record|flat discs]] with a spiral groove running from the periphery to near the center, coining the term ''gramophone'' for disc record players, which is predominantly used in many languages. Later improvements through the years included modifications to the turntable and its drive system, the [[Magnetic cartridge|stylus]] or needle, pickup system, and the sound and [[Equalization (audio)|equalization]] systems.

The disc [[phonograph record]] was the dominant commercial audio distribution format throughout most of the 20th century, and phonographs became the first example of [[home audio]] that people owned and used at their residences.<ref>https://pure.manchester.ac.uk/ws/portalfiles/portal/26992666/POST-PEER-REVIEW-PUBLISHERS.PDF</ref> In the 1960s, the use of [[8-track tape|8-track cartridges]] and [[cassette tape]]s were introduced as alternatives. By 1987, phonograph use had declined sharply due to the popularity of cassettes and the rise of the [[compact disc]]. However, records have undergone a [[vinyl revival|revival since the late 2000s]]. This resurgence has much to do with vinyl records' sparing use of audio processing, resulting in a more natural sound on high-quality replay equipment, compared to many digital releases that are highly processed for portable players in high-noise environmental conditions. However, unlike "plug-and-play" digital audio, vinyl record players have user-serviceable parts, which require attention to tonearm alignment and the wear and choice of stylus, the most critical component affecting turntable sound.<ref>"Better Sound from your Phonograph" ISBN 979-8218067304</ref>

== Terminology ==
The terminology used to describe record-playing devices is not uniform across the English-speaking world. In modern contexts, the playback device is often referred to as a "turntable", "record player", or "[[record changer]]". Each of these terms denotes distinct items. When integrated into a [[Disc jockey|DJ]] setup with a [[DJ mixer|mixer]], turntables are colloquially known as "decks".<ref>{{cite web |title=DJ Jargon, DJ Dictionary, DJ Terms, DJ Terminology, DJ Glossary of terms – DJ School UK |url=https://djschooluk.org.uk/dj-jargon-dj-dictionary-dj-terms-dj-terminology-dj-glossary-of-terms/ |url-status=dead |archive-url=https://web.archive.org/web/20191204201732/https://djschooluk.org.uk/dj-jargon-dj-dictionary-dj-terms-dj-terminology-dj-glossary-of-terms/ |archive-date=2019-12-04 |access-date=2019-12-04 |language=en-GB}}</ref> In later versions of electric phonographs, commonly known since the 1940s as record players or turntables, the movements of the stylus are transformed into an [[electrical signal]] by a [[transducer]]. This signal is then converted back into sound through a [[loudspeaker]].<ref>{{cite web |last=Hockenson |first=Lauren |date=20 December 2012 |title=This Is How a Turntable Really Works |url=https://mashable.com/2012/12/20/dj-turntable/ |url-status=live |archive-url=https://web.archive.org/web/20191204200225/https://mashable.com/2012/12/20/dj-turntable/ |archive-date=2019-12-04 |access-date=2019-12-04 |website=Mashable |language=en}}</ref>

The term "phonograph", meaning "sound writing", originates from the [[Ancient Greek|Greek]] words φωνή (phonē, meaning 'sound' or 'voice') and γραφή (graphē, meaning 'writing'). Similarly, the terms "gramophone" and "graphophone" have roots in the Greek words γράμμα (gramma, meaning 'letter') and φωνή (phōnē, meaning 'voice').

In [[British English]], "gramophone" may refer to any sound-reproducing machine that utilizes [[disc records]]. These were introduced and popularized in the UK by the [[Gramophone Company]]. Initially, "gramophone" was a proprietary [[trademark]] of the company, and any use of the name by competing disc record manufacturers was rigorously challenged in court. However, in 1910, an English court decision ruled that the term had become generic;<ref>{{cite web |date=1910-07-05 |title=Application by the Gramophone Company to register "Gramophone" as a trade mark |url=http://rpc.oxfordjournals.org/content/27/27/689.full.pdf |url-status=dead |archive-url=https://wayback.archive-it.org/all/20190412094028/http://rpc.oxfordjournals.org/content/27/27/689.full.pdf |archive-date=2019-04-12 |website=Reports of Patent, Design and Trade Mark Cases |publisher=The Illustrated Official Journal}}</ref>

In [[American English]], "phonograph", properly specific to machines made by Edison, was sometimes used in a generic sense as early as the 1890s to include cylinder-playing machines made by others. But it was then considered strictly incorrect to apply it to [[Emile Berliner]]'s Gramophone, a different machine that played nonrecordable discs (although Edison's original Phonograph patent included the use of discs.<ref>{{cite web  |url=https://intertique.com/TheEdisonDiamondDiscPhonograph.html |title=The Edison Diamond Disc Phonograph – History, Identification, Repair  |access-date=17 March 2020  |archive-date=17 March 2020|archive-url=https://web.archive.org/web/20200317051242/https://intertique.com/TheEdisonDiamondDiscPhonograph.html |url-status=live}}</ref>)

=== Paleophone ===
[[Charles Cros]], a French poet and amateur scientist, is the first person known to have made the conceptual leap from recording sound as a traced line to the theoretical possibility of reproducing the sound from the tracing and then to devising a definite method for accomplishing the reproduction. On April 30, 1877, he deposited a sealed envelope containing a summary of his ideas with the [[French Academy of Sciences]], a standard procedure used by scientists and inventors to establish [[Scientific priority|priority of conception]] of unpublished ideas in the event of any later dispute.<ref name="RBNF">{{citation |url=http://www.cairn.info/zen.php?ID_ARTICLE=RBNF_033_0020 |title=L'impression du son |archive-url=https://web.archive.org/web/20150928231926/http://www.cairn.info/zen.php?ID_ARTICLE=RBNF_033_0020 |archive-date=2015-09-28 |work=Revue de la BNF |date=2009 |publisher=Bibliothèque nationale de France |isbn=9782717724301 |issue=33 |url-status=live}}</ref>

An account of his invention was published on October 10, 1877, by which date Cros had devised a more direct procedure: the recording stylus could scribe its tracing through a thin coating of acid-resistant material on a metal surface and the surface could then be etched in an acid bath, producing the desired groove without the complication of an intermediate photographic procedure.<ref>{{cite web | title = www.phonozoic.net | work = Transcription and translation of October 10, 1877 article on Cros "phonographe". | url = http://phonozoic.net/n0131.htm | url-status = live | archive-url = https://web.archive.org/web/20110724004724/http://phonozoic.net/n0131.htm | archive-date = July 24, 2011 }}</ref> The author of this article called the device a {{lang|fr|phonographe}}, but Cros himself favored the word {{lang|fr|paleophone}}, sometimes rendered in French as {{lang|fr|voix du passé}} ('voice of the past').{{citation needed|date=June 2022}}

Cros was a poet of meager means, not in a position to pay a machinist to build a working model, and largely content to bequeath his ideas to the [[public domain]] free of charge and let others reduce them to practice, but after the earliest reports of Edison's presumably independent invention crossed the Atlantic he had his sealed letter of April 30 opened and read at the December 3, 1877 meeting of the French Academy of Sciences, claiming due scientific credit for priority of conception.<ref>{{cite web | title = www.phonozoic.net | work = Transcription and translation of December 3, 1877 unsealing of April, 1877 Cros deposit. | url = http://WWW.phonozoic.net/n0130.htm | url-status = live | archive-url = https://web.archive.org/web/20110724005535/http://www.phonozoic.net/n0130.htm | archive-date = July 24, 2011 }}</ref>

Throughout the first decade (1890–1900) of commercial production of the earliest crude disc records, the direct acid-etch method first invented by Cros was used to create the metal master discs, but Cros was not around to claim any credit or to witness the humble beginnings of the eventually rich phonographic library he had foreseen. He had died in 1888 at the age of 45.<ref>{{Cite news|url=https://www.britannica.com/biography/Charles-Cros|title=Charles Cro: French inventor and poet|work=[[Encyclopedia Britannica]]|access-date=2018-03-09|language=en|archive-date=2018-03-09|archive-url=https://web.archive.org/web/20180309183518/https://www.britannica.com/biography/Charles-Cros|url-status=live}}</ref>

By 1890, record manufacturers had begun using a rudimentary duplication process to mass-produce their product. While the live performers recorded the master phonograph, up to ten tubes led to blank cylinders in other phonographs. Until this development, each record had to be custom-made. Before long, a more advanced [[pantograph]]-based process made it possible to simultaneously produce 90–150 copies of each record. However, as demand for certain records grew, popular artists still needed to re-record and re-re-record their songs. Reportedly, the medium's first major African-American star [[George W. Johnson (singer)|George Washington Johnson]] was obliged to perform his "[[The Laughing Song]]" (or the separate "The Whistling Coon")<ref>University of California.

The 1860 phonautogram had not until then been played, as it was only a transcription of sound waves into graphic form on paper for visual study.

A recording made on a sheet of tinfoil at an 1878 demonstration of Edison's phonograph in St. Louis, Missouri, has been played back by optical scanning and digital analysis.

== Improvements at the Volta Laboratory ==
{{Main|Volta Laboratory and Bureau#Sound recording and phonograph development}}
[[Alexander Graham Bell]] and his two associates took Edison's [[tinfoil]] phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's [[Volta Laboratory]] in Washington, D. C., in 1879, and continued until they were granted basic patents in 1886 for recording in wax.<ref name="Newville">Newville, Leslie J.

Retrieved from ProjectGutenberg.org.</ref>

Although Edison had [[Thomas Edison#Beginning his career|invented the phonograph]] in 1877, the fame bestowed on him for this invention was not due to its efficiency. Recording with his tinfoil phonograph was too difficult to be practical, as the tinfoil tore easily, and even when the stylus was properly adjusted, its reproduction of sound was distorted, and good for only a few playbacks; nevertheless Edison had discovered the idea of [[sound recording]]. However immediately after his discovery he did not improve it, allegedly because of an agreement to spend the next five years developing the [[History of electric power transmission#Early high voltage and commercial systems|New York City electric light and power]] system.<ref name="Newville"/>

=== Volta's early challenge ===
Meanwhile, Bell, a [[scientist]] and experimenter at heart, was looking for new worlds to conquer after having patented the [[telephone]]. According to [[Sumner Tainter]], it was through [[Gardiner Hubbard|Gardiner Green Hubbard]] that Bell took up the phonograph challenge. Bell had married [[Mabel Gardiner Hubbard|Hubbard's daughter Mabel]] in 1879 while Hubbard was president of the Edison Speaking Phonograph Co., and his organization, which had purchased the Edison patent, was financially troubled because people did not want to buy a machine that seldom worked well and proved difficult for the average person to operate.<ref name="Newville"/>

=== Volta Graphophone ===
{{See also|Graphophone}}
[[File:Transcription using cylinder phonograph.png|thumb|left| A 'G' (Graham Bell) model Graphophone being played back by a typist after its cylinder had recorded dictation.]]
The sound vibrations had been indented in the wax that had been applied to the Edison phonograph. The following was the text of one of their recordings: "There are more things in heaven and earth, Horatio, than are dreamed of in your philosophy. I am a Graphophone and my mother was a phonograph."<ref>''[[The Washington Herald]]'', October 28, 1937.</ref> Most of the disc machines designed at the Volta Lab had their disc mounted on vertical turntables. The explanation is that in the early experiments, the turntable, with disc, was mounted on the shop lathe, along with the recording and reproducing heads. Later, when the complete models were built, most of them featured vertical turntables.<ref name="Newville"/>

One interesting exception was a horizontal seven inch turntable. The machine, although made in 1886, was a duplicate of one made earlier but taken to Europe by [[Chichester Bell]]. Tainter was granted {{US patent|385886}} on July 10, 1888. The playing arm is rigid, except for a pivoted vertical motion of 90 degrees to allow removal of the record or a return to starting position. While recording or playing, the record not only rotated, but moved laterally under the stylus, which thus described a spiral, recording 150 grooves to the inch.<ref name="Newville"/>

The basic distinction between the Edison's first phonograph patent and the Bell and Tainter patent of 1886 was the method of recording. Edison's method was to indent the sound waves on a piece of tin foil, while Bell and Tainter's invention called for cutting, or "engraving", the sound waves into a wax record with a sharp recording stylus.<ref name="Newville"/>

===Graphophone commercialization===

In 1885, when the Volta Associates were sure that they had a number of practical inventions, they filed [[patent]] applications and began to seek out investors. The [[Volta Graphophone Company]] of Alexandria, Virginia, was created on January 6, 1886, and incorporated on February 3, 1886. It was formed to control the patents and to handle the commercial development of their sound recording and reproduction inventions, one of which became the first [[Dictaphone]].<ref name="Newville"/>

After the Volta Associates gave several demonstrations in the City of Washington, businessmen from [[Philadelphia]] created the [[American Graphophone Company]] on March 28, 1887, in order to produce and sell the machines for the budding phonograph marketplace.<ref name=ERS/> The Volta Graphophone Company then merged with American Graphophone,<ref name=ERS>Hoffmann, Frank W. & Ferstler, Howard.

The work of the Volta Associates laid the foundation for the successful use of [[Dictation machine|dictating machines]] in business, because their wax recording process was practical and their machines were durable.

==Disc vs. cylinder as a recording medium==
Discs (that aren't re-recordable) are not inherently better than cylinders at providing audio fidelity. Rather, the advantages of the format are seen in the manufacturing process: discs can be stamped, and the matrixes to stamp disc can be shipped to other printing plants for a global distribution of recordings; cylinders could not be stamped until 1901–1902, when the gold moulding process was introduced by Edison.<ref name="the cylinder preservation and digitalization project">{{cite web|title=cylinder history|date=16 November 2005|url=http://cylinders.library.ucsb.edu/history-goldmoulded.php|access-date=17 June 2012|url-status=live|archive-url=https://web.archive.org/web/20121209071459/http://cylinders.library.ucsb.edu/history-goldmoulded.php|archive-date=9 December 2012}}</ref>

[[File:VictorVPhonograph.jpg|thumb|left|upright|A Victor V phonograph, circa 1907]]
Through experimentation, in 1892 Berliner began commercial production of his disc records and "gramophones". His "[[gramophone record]]" was the first disc record to be offered to the public. They were {{convert|5|in|cm|spell=in}} in diameter and recorded on one side only. Seven-inch (17.5&nbsp;cm) records followed in 1895. Also in 1895 Berliner replaced the hard rubber used to make the discs with a shellac compound.<ref>{{cite web|title=the early gramophone|url=http://homepage.mac.com/oldtownman/recording/berliner.html|access-date=17 June 2012|url-status=dead|archive-url=https://web.archive.org/web/20120113014850/http://homepage.mac.com/oldtownman/recording/berliner.html|archive-date=13 January 2012}}</ref> Berliner's early records had poor sound quality, however.

==Dominance of the disc record==
[[File:Portable 78 rpm record player.jpg|thumb|right|A 1930s portable wind-up gramophone from [[EMI]] ([[His Master's Voice]])]]
In the 1930s, [[Gramophone record|vinyl]] (originally known as vinylite) was introduced as a record material for radio [[transcription disc]]s, and for radio commercials. At that time, virtually no discs for home use were made from this material. Vinyl was used for the popular 78-rpm [[V-discs]] issued to US soldiers during [[World War II]]. This significantly reduced breakage during transport. The first commercial vinylite record was the set of five 12" discs "[[Prince Igor]]" (Asch Records album S-800, dubbed from Soviet masters in 1945). Victor began selling some home-use vinyl 78s in late 1945; but most 78s were made of a [[shellac]] compound until the 78-rpm format was completely phased out. (Shellac records were heavier and more brittle.) 33s and 45s were, however, made exclusively of vinyl, with the exception of some 45s manufactured out of [[polystyrene]].<ref>Peter A Soderbergh, "Olde Records Price Guide 1900–1947", Wallace–Homestead Book Company, Des Moines, Iowa, 1980, pp.193–194</ref>

The October 1955 issue of ''Radio & Television News'' magazine (page 41), had a full page detailed article on Philco's new consumer product. The all-transistor portable phonograph TPA-1 and TPA-2 models played only 45rpm records and used four 1.5 volt "D" batteries for their power supply. The "TPA" stands for "Transistor Phonograph Amplifier". Their circuitry used three Philco germanium PNP alloy-fused junction audio frequency transistors.

In a belt-drive turntable the [[Electric motor|motor]] is located off-center from the platter, either underneath it or entirely outside of it, and is connected to the platter or counter-platter by a [[Belt (mechanical)|drive belt]] made from [[Elastomer|elastomeric]] material.

The direct-drive turntable was invented by Shuichi Obata, an engineer at [[Panasonic|Matsushita]] (now Panasonic).<ref name="billboard">''[[Billboard (magazine)|Billboard]]'', May 21, 1977, [https://books.google.com/books?id=XCMEAAAAMBAJ&pg=PT140 page 140]</ref> In 1969, Matsushita released it as the [[Technics (brand)|Technics]] SP-10,<ref name="oxford">Trevor Pinch, Karin Bijsterveld, [https://books.google.com/books?id=KuRfLG0IedYC&pg=PA515 ''The Oxford Handbook of Sound Studies'', page 515], [[Oxford University Press]]</ref> the first direct-drive turntable on the market.<ref name="reverb">{{cite web|title=History of the Record Player Part II: The Rise and Fall|url=https://reverb.com/news/history-of-the-record-player-part-ii-the-rise-and-fall|website=[[Reverb.com]]|date=October 2015 |accessdate=5 June 2016}}</ref> The most influential direct-drive turntable was the [[Technics SL-1200]],<ref name="wired">[https://www.wired.com/2002/05/blackbox/ Six Machines That Changed The Music World], ''[[Wired (magazine)|Wired]]'', May 2002</ref> which, following the spread of [[turntablism]] in [[hip hop]] culture, became the most widely-used turntable in DJ culture for several decades.<ref name="wired" />

==Arm systems==

In some high quality equipment the arm carrying the pickup, known as a tonearm, is manufactured separately from the motor and turntable unit. Companies specialising in the manufacture of tonearms include the English company [[SME Limited|SME]].

===Cue lever===
More sophisticated turntables were (and still are) frequently manufactured so as to incorporate a "cue lever", a device that mechanically lowers the tonearm on to the record. It enables the user to locate an individual track more easily, to pause a record, and to avoid the risk of scratching the record, which may require practice to avoid when lowering the tonearm manually.<ref>{{cite web |date=29 March 2023 |title=What is a cue lever on a turntable?

===Linear tracking===
Early developments in linear turntables were from Rek-O-Kut (portable lathe/phonograph) and Ortho-Sonic in the 1950s, and Acoustical in the early 1960s. These were eclipsed by more successful implementations of the concept from the late 1960s through the early 1980s.<ref>{{cite web |author=Rudolf A.

==Pickup systems==<!--[[Phono cartridge]] and [[Phonograph cartridge]] redirect here-->
[[File:NadelAufPlatte.JPG|thumb|right|Typical magnetic cartridge]]
The pickup or cartridge is a [[transducer]] that converts mechanical vibrations from a stylus into an electrical signal. The electrical signal is [[Amplifier|amplified]] and converted into sound by one or more [[loudspeaker]]s. Crystal and ceramic pickups that use the [[piezoelectric effect]] have largely been replaced by [[magnetic cartridge]]s.

The pickup includes a stylus with a small [[diamond]] or [[sapphire]] tip that runs in the record groove. The stylus eventually becomes worn by contact with the groove, and it is usually replaceable.

Styli are classified as spherical or elliptical, although the tip is actually shaped as a half-sphere or a half-[[ellipsoid]]. Spherical styli are generally more robust than other types, but do not follow the groove as accurately, giving diminished high frequency response. Elliptical styli usually track the groove more accurately, with increased high frequency response and less distortion. For DJ use, the relative robustness of spherical styli make them generally preferred for back-cuing and scratching. There are a number of derivations of the basic elliptical type, including the shibata or fine line stylus, which can more accurately reproduce high frequency information contained in the record groove. This is especially important for playback of quadraphonic recordings.<ref>https://www.ortofon.com/media/14912/everything_you_need_to_know_about_styli_types.pdf</ref>

=== Optical readout ===
A few specialist [[laser turntable]]s read the groove optically using a laser pickup. Since there is no physical contact with the record, no wear is incurred. However, this "no wear" advantage is debatable, since vinyl records have been tested to withstand even 1200 plays with no significant audio degradation, provided that it is played with a high quality cartridge and that the surfaces are clean.<ref>Loescher, Long-Term Durability of Pickup Diamonds and Records, Journal of the Audio Engineering Society, vol 22, issue 10, pp 800</ref>

An alternative approach is to take a high-resolution photograph or scan of each side of the record and interpret the image of the grooves using [[computer software]]. An amateur attempt using a flatbed scanner lacked satisfactory fidelity.<ref>[http://www.cs.huji.ac.il/~springer/ Digital Needle – A Virtual Gramophone] {{webarchive|url=https://web.archive.org/web/20031229221243/http://www.cs.huji.ac.il/~springer/ |date=2003-12-29 }} URL accessed March 31, 2007</ref> A professional system employed by the [[Library of Congress]] produces excellent quality.<ref>[https://www.npr.org/templates/story/story.php?storyId=11851842 You Can Play the Record, but Don't Touch] {{webarchive|url=https://web.archive.org/web/20070812180736/http://www.npr.org/templates/story/story.php?storyId=11851842 |date=2007-08-12 }} URL accessed April 25, 2008</ref>

== Stylus ==
[[File:RedDevilNeedle.jpg|thumb|left|Stylus for [[jukebox]] using [[shellac]] 78 rpm records, 1940s]]

A development in stylus form came about by the attention to the [[Compatible Discrete 4|CD-4]] [[quadraphonic]] sound modulation process, which requires up to 50&nbsp;kHz frequency response, with cartridges like [[Technics (brand)|Technics]] EPC-100CMK4 capable of playback on frequencies up to 100&nbsp;kHz. This requires a stylus with a narrow side radius, such as 5&nbsp;μm (or 0.2 [[Thou (length)|mil]]). A narrow-profile elliptical stylus is able to read the higher frequencies (greater than 20&nbsp;kHz), but at an increased wear, since the contact surface is narrower. For overcoming this problem, the Shibata stylus was invented around 1972 in Japan by Norio Shibata of JVC.<ref>US Patent 3774918</ref>

The Shibata-designed stylus offers a greater contact surface with the groove, which in turn means less pressure over the vinyl surface and thus less wear. A positive side effect is that the greater contact surface also means the stylus reads sections of the vinyl that were not touched (or "worn") by the common spherical stylus. In a demonstration by JVC<ref>{{cite web |url=http://www.johana.com/~johana/dorren/cd-4paper4.pdf |title=Johana.com |access-date=2011-10-12 |url-status=dead |archive-url=https://web.archive.org/web/20110713112415/http://www.johana.com/~johana/dorren/cd-4paper4.pdf |archive-date=2011-07-13 }}</ref> records "worn" after 500 plays at a relatively high 4.5 gf tracking force with a spherical stylus, played "as new" with the Shibata profile.{{citation needed|date=June 2022}}

Other advanced stylus shapes appeared following the same goal of increasing contact surface, improving on the Shibata. Chronologically: "Hughes" Shibata variant (1975),<ref>US Patent 3871664</ref> "Ogura" (1978),<ref>US Pat. 4105212</ref> Van den Hul (1982).<ref>US Pat. 4365325</ref> Such a stylus may be marketed as "Hyperelliptical" (Shure), "Alliptic", "Fine Line" (Ortofon), "Line contact" (Audio Technica), "Polyhedron", "LAC", or "Stereohedron" (Stanton).<ref name="vinylengine.com">{{cite web |url=http://www.vinylengine.com/phpBB2/viewtopic.php?t=22894&start=0 |title=Vinylengine.com |publisher=Vinylengine.com |date=2009-11-09 |access-date=2011-10-12 |url-status=live |archive-url=https://web.archive.org/web/20110717210500/http://www.vinylengine.com/phpBB2/viewtopic.php?t=22894&start=0 |archive-date=2011-07-17 }}</ref>

A keel-shaped diamond stylus appeared as a byproduct of the invention of the [[Capacitance Electronic Disc|CED Videodisc]]. This, together with laser-diamond-cutting technologies, made possible the "ridge" shaped stylus, such as the Namiki (1985)<ref>US Patent 4521877</ref> design, and Fritz Gyger (1989)<ref>US Patent 4855989</ref> design. This type of stylus is marketed as "MicroLine" (Audio technica), "Micro-Ridge" (Shure), or "Replicant" (Ortofon).<ref name="vinylengine.com"/>

To address the problem of steel needle wear upon [[Phonograph record|records]], which resulted in the cracking of the latter, [[RCA Victor]] devised unbreakable records in 1930, by mixing polyvinyl chloride with plasticisers, in a proprietary formula they called Victrolac, which was first used in 1931, in motion picture discs.<ref>Barton, F.C. (1932 [1931]). ''Victrolac Motion Picture Records''. Journal of the Society of Motion Picture Engineers, April 1932 '''18'''(4):452–460 (accessed at archive.org on 5 August 2011)</ref>

==Equalization==
Since the late 1950s, almost all phono input stages have used the RIAA equalization standard. Before settling on that standard, there were many different equalizations in use, including EMI, HMV, Columbia, Decca FFRR, NAB, Ortho, BBC transcription, etc. Recordings made using these other equalization schemes typically sound odd if they are played through a RIAA-equalized preamplifier. High-performance (so-called "multicurve disc") preamplifiers, which include multiple, selectable equalizations, are no longer commonly available. However, some vintage preamplifiers, such as the [[LEAK]] varislope series, are still obtainable and can be refurbished. Newer preamplifiers like the Esoteric Sound Re-Equalizer or the K-A-B MK2 Vintage Signal Processor are also available.<ref>Powell, James R., Jr. and Randall G. Stehle.

New interest in records has led to the development of turntables with additional modern features. USB turntables have a built-in audio interface, which transfers the analog sound directly to the connected computer.<ref>{{cite web |url=http://recordplayerreviews.org/vinyl-conversion-to-digital/ |title=Vinyl to USB Conversion |publisher=recordplayerreviews.org |url-status=dead |archive-url=https://web.archive.org/web/20160730142506/http://recordplayerreviews.org/vinyl-conversion-to-digital/ |archive-date=2016-07-30 }}</ref> Some USB turntables transfer the audio without equalization, but are sold with software that allows the EQ of the transferred audio file to be adjusted. There are also many turntables on the market designed to be plugged into a computer via a [[USB]] port for [[needle drop (audio)|needle dropping]] purposes.<ref>{{cite web |url=http://www.knowzy.com/usb-turntable-comparison.htm |title=USB turntable comparison |publisher=Knowzy.com |date=2008-12-01 |access-date=2011-10-12 |url-status=live |archive-url=https://web.archive.org/web/20110713162826/http://www.knowzy.com/usb-turntable-comparison.htm |archive-date=2011-07-13 }}</ref>

Modern turntables have also been released featuring [[Bluetooth]] technology to output a record's sound wirelessly through speakers.<ref name=":0" /> Sony have also released a high-end turntable with an [[analog-to-digital converter]] to convert the sound from a playing record into a 24-bit [[high-resolution audio]] file in [[Direct Stream Digital|DSD]] or [[WAV]] formats.<ref>{{Cite web |last=Cox |first=Jamieson |date=2016-01-06 |title=This new Sony turntable is turnt |url=https://www.theverge.com/2016/1/5/10713652/sony-ps-hx500-turntable-high-res-audio-ces-2016 |access-date=2024-05-04 |website=The Verge |language=en}}</ref>
