Flexi disc

Flexi discs like this Interface Age "Floppy ROM" program sheet were occasionally included as inserts in computer hobbyist and video game magazines during the late 1970s and early 1980s.

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.[1][2] They were very popular among children and teenagers and mass-produced by the state publisher in the Soviet government.[citation needed]
