scope:

This standard provides technical requirements for still video floppy disk systems which use a magnetic disk in a jacket, known as a still video floppy disk. In these systems analogue picture, time-compressed analogue audio sounds after/or digital data information are recorded separately or together on a magnetic disk. There are two formats of analogue recording. One is for 525 line - 60 field systems and the other for 625 line - 50 field systems. There are 50 main tracks and one cue track on the disk. Analogue picture, time-compressed sounds, and/or digital data information are recorded on the main tracks.
