The flexi disc (also known as a phonosheet, Sonosheet or Soundsheet, a trademark) is a phonograph record made of a thin, flexible vinyl sheet with a molded-in spiral stylus groove, and is designed to be playable on a normal phonograph turntable.
Flexible records were commercially introduced as the Eva-tone Soundsheet in 1962. They were very popular among children and teenagers and mass-produced by the state publisher in the Soviet government.
History
Before the advent of the compact disc, flexi discs were sometimes used as a means to include sound with printed material such as magazines and music instruction books. A flexi disc could be moulded with speech or music and bound into the text with a perforated seam, at very little cost and without any requirement for a hard binding. One problem with using the thinner vinyl was that the stylus's weight, combined with the flexi disc's low mass, would sometimes cause the disc to stop spinning on the turntable and become held in place by the stylus. For this reason, most flexi discs had a spot on the face of the disc for a coin, or other small, flat, weighted object to increase the friction with the turntable surface and enforce consistent rotation. If the turntable's surface is not completely flat, it is recommended that the flexi disc be placed on top of a full sized record.
In Japan, starting in the early 1960s, Asahi Sonorama published the monthly Asahi Sonorama magazine which included an inserted flexi disc ("Sonosheet").
Every year between 1963 and 1969, The Beatles made a special Christmas recording which was made into a flexi disc and sent to members of their fan club. While the earlier discs largely contained 'thank you' messages to their fans, the later Christmas flexis were used as an outlet for the Beatles to explore more experimental areas; the 1967 disc, for example, became a pastiche of a BBC Radio show and even included a specially recorded song entitled "Christmas Time (Is Here Again)."
In 1964, the National Geographic Society released Song and Garden Birds of North America which included a 6 sound discs (12-sides) bound alternating with pages giving the titles and birds on the recordings. The work was done by Arthur A. Allen and Peter Paul Kellogg of the Cornell Laboratory of Ornithology.
The August 1965 issue of National Geographic Magazine included a soundsheet of the funeral of Sir Winston Churchill narrated by David Brinkley. The recording has the sounds of the funeral procession to St. Paul's, a hymn sung by the leaders of the world, and an excerpt of the funeral sermon. Excerpts from various recordings of Churchill's speeches are included. The recording ends with bagpipes accompanying Churchill's coffin to the funeral barge on the Thames, as the public phase of the funeral ends.
During the 1970s, MAD magazine included Soundsheets in several special editions. One was a dramatization of Gall in the Family Fare, its parody of All in the Family, packaged with MAD Super Special #11 (1973). The Summer 1980 edition of MAD Super Special (published in 1979) featured "It's a Super-Spectacular Day", a song with eight different versions pressed into eight concentric grooves; which version was played depended on where the needle was dropped onto the disc. Another issue included "It's a Gas", a song whose lyrics were belches. There was also a "Mad Disco" special issue containing a Soundsheet.
ABBA/Live 77 was a special single-sided promo gold flexi disc given as a bonus to children who sold magazines and books at Christmas for Jultidningsförlaget, a publishing company using door sales as their main distribution channel. The disc contained excerpts from the Swedish group's recent concert appearance in Australia.
A two-sided flexible sheet record of the songs of humpback whales (produced by Roger Payne) was included with the January 1979 issue of National Geographic Magazine. With a production order of 10,500,000 copies, it became the largest single press run of any record at the time.
Computer magazines began to provide software in audio form "Vinyl Data" on flexi discs from June 1979 until 1986.
While flexi-discs were usually just used as occasional giveaways, from 1980 to 1982, Flexipop made a speciality of giving away such a disc with each edition. Compact discs and the internet have rendered flexi discs largely obsolete, but gimmick discs are still produced occasionally: Amelia's Magazine included a one-sided Libertines flexi of What Katie Did.
American manufacturer Eva-Tone, believed to be one of the last manufacturers of flexi discs, stopped production of the product in August 2000.
