A flexi disc is a phonograph record in the form of a thin flexible vinyl sheet. They were introduced commercially in the US in 1962 as the Eva-tone Soundsheet, but some 78 rpm flexi discs were available prior to that in the UK, and in the Soviet Union, old X-ray films were used to make flexi discs to distribute underground music.
They were used as a means of including speech or music in printed publications such as magazines, and could be bound in the publication with a perforated seam. Although the grooves were circular, the sheet could be square or round.
In the late 1970s and early 1980s, computer programs were sometimes encoded on flexi discs and distributed in form of so-called Floppy ROMs in magazines, in a similar way to Compact Cassettes and later CD-ROMs.
Whilst Eva-tone ceased production in 2000, music flexi discs are still being released in very small numbers.
