A phonograph, in its later forms also called a gramophone or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. 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 "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones.
A jukebox is a partially automated music-playing device, usually a coin-operated machine, that plays a patron's selection from self-contained media. The classic jukebox has buttons with letters and numbers on them, which are used to select specific records. Some may use compact discs instead. Disc changers are similar devices for home use; they are small enough to fit on a shelf and can hold up to hundreds of discs, allowing them to be easily removed, replaced, or inserted by the user.
Phonograph cylinders are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their heyday, these hollow cylindrical objects have an audio recording engraved on the outside surface, which can be reproduced when they are played on a mechanical cylinder phonograph. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium.
An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album or LP record. Contemporary EPs generally contain four to five tracks, and are considered "less expensive and time-consuming" for an artist to produce than an album. An EP originally referred to specific types of records other than 78 rpm standard play (SP) and LP, but it is now applied to mid-length CDs and downloads as well. In K-pop they are usually referred to as mini albums. Ricardo Baca of The Denver Post said, "EPs—originally extended-play 'single' releases that are shorter than traditional albums—have long been popular with punk and indie bands." In the United Kingdom, the Official Chart Company defines a boundary between EP and album classification at 25 minutes of maximum length and no more than four tracks.
A phonograph record, a vinyl record, or simply a record or vinyl is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. For about half a century, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s, polyvinyl chloride (PVC) became common, the "vinyl records" of the late 20th century.
The Victor Talking Machine Company was an American recording company and phonograph manufacturer that operated independently from 1901 until 1929 when the company was purchased by the Radio Corporation of America and subsequently operated as the RCA Victor Division of the Radio Corporation of America.
Blue Amberol Records was the trademark name for cylinder records manufactured by Thomas A. Edison, Inc. in the US from 1912 to 1929. They replaced the 4-minute black wax Amberol cylinders introduced in 1908, which had replaced the 2-minute wax cylinders that had been the standard format since the late 1880s. Blue Amberols can play for as long as 4 minutes and 45 seconds and have a surface layer of the "indestructible" plastic celluloid, which Edison tinted a trademark blue color. Edison brand phonographs designed to play Amberol cylinders were named Amberolas.
The Edison Diamond Disc Record is a type of phonograph record marketed by Thomas A. Edison, Inc. on their Edison Record label from 1912 to 1929. They were named Diamond Discs because the matching Edison Disc Phonograph was fitted with a permanent conical diamond stylus for playing them. Diamond Discs were incompatible with lateral-groove disc record players, e.g. the Victor Victrola, the disposable steel needles of which would damage them while extracting hardly any sound. Uniquely, they are just under 1⁄4 in thick.
An album is a collection of audio recordings issued on a medium such as compact disc (CD), vinyl (record), audio tape, or digital. Albums of recorded sound were developed in the early 20th century as individual 78 rpm records collected in a bound book resembling a photo album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+1⁄3 rpm.
The overwhelming majority of records manufactured have been of certain sizes, playback speeds, and appearance. However, since the commercial adoption of the gramophone record, a wide variety of records have also been produced that do not fall into these categories, and they have served a variety of purposes.
A record changer or autochanger is a device that plays several phonograph records in sequence without user intervention. Record changers first appeared in the late 1920s, and were common until the 1980s.
"Discothèque" is a song by Irish rock band U2. It is the opening track on their 1997 album, Pop, and was released as its lead single on 3 February 1997. The song exhibits influences from electronic dance music, characteristic of the band's musical direction in the 1990s. The music video, directed by Stéphane Sednaoui, was set inside of a mirrorball and featured the band members dressed as members of the disco group the Village People.
The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods:
Seeburg was an American design and manufacturing company of automated musical equipment, such as orchestrions, jukeboxes, and vending equipment. Before it began manufacturing its signature suite of jukebox products, Seeburg was considered to be one of the "big four" of the top coin-operated phonograph companies alongside AMI, Wurlitzer, and Rock-Ola. At the height of jukebox popularity, Seeburg machines were synonymous with the technology and a major quotidian brand of American teenage life. The company went out of business after being sold to Stern Electronics in 1982.
The Rock-Ola Manufacturing Corporation is an American developer and manufacturer of juke boxes and related machinery. It was founded in 1927 by Coin-Op pioneer David Cullen Rockola to manufacture slot machines, scales, and pinball machines. The firm later produced parking meters, furniture, arcade video games, and firearms, but became best known for its jukeboxes.
Highway Hi-Fi was a system of proprietary players and seven-inch phonograph records with standard LP center holes designed for use in automobiles. Designed and developed by Peter Goldmark, who also developed the LP microgroove, the discs utilized 135 grams of vinyl each, enough to press a standard 10-inch LP.
The LP is an analog sound storage medium, a phonograph record format characterized by: a speed of 33+1⁄3 rpm; a 12- or 10-inch diameter; use of the "microgroove" groove specification; and a vinyl composition disk. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire US record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums, during a period in popular music known as the album era. Beginning in the late 1970s, LP sales began to decline because of the increasing popularity of Compact Cassettes, then in the 1980s of compact discs. By 1988, the latter format began to outsell LPs.
The vertical cut recording process is an early method of audio recording by which a stylus cuts a vertical groove into a phonograph record. This is in contrast to the lateral recording system which uses a stylus that cuts side-to-side across a record. The vertical recording process, also known as the hill and dale process, was used to record phonograph cylinder records as well as Edison Disc Records, Pathé disc records, and disc records made by numerous smaller companies. Vertical cut recording was also used as a means of copyright protection by the early Muzak 16-inch background music discs.
Matthew "Mat" Taylor, better known by his YouTube handle Techmoan, is an British YouTuber and blogger, specializing in consumer tech reviews and retrotech documentaries about technology of historical interest.
Electrical transcriptions are special phonograph recordings made exclusively for radio broadcasting, which were widely used during the "Golden Age of Radio". They provided material—from station-identification jingles and commercials to full-length programs—for use by local stations, which were affiliates of one of the radio networks.
