The
flexi disc (also known as a
phonosheet 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, and were very popular among children and teenagers and mass-produced by the state publisher in the
Soviet government.
