Video Single Disc

Video Single Disc (VSD) is a disc-based format that carried the same analog video information as a LaserDisc, but on a 12-centimetre (4.75 inch) diameter CD-DA-sized disc. It was spearheaded by Sony and was released in Japan in 1990. It was a new variety of laserdisc and variation on the CD Video (CD-V) format, except that VSD disc carried only a video track (of up to 5 minutes' duration), and its associated audio, with no CD-compatible partition. The disc is the same size as a standard CD and holds five minutes of video with digital sound. It did not have any additional audio tracks like CD-V. Like CD-V, VSD discs could be played back by multi-disc or LaserDisc players that had VSD playback capability.
