BS EN 61122 discusses specification for a still video floppy disk magnetic recording system. BS EN 61122 provides technical requirements for still video floppy disk systems that use a magnetic disk in a jacket, known as a still video floppy disk. In these systems, analogue pictures, time-compressed analogue audio sounds and/or digital data information are recorded separately or together on a magnetic disk.
BS EN 61122 on still video floppy disk magnetic recording system is useful for:
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. The information recorded on the cue track can be used primarily for control purposes relating to the information on the main tracks.
BS EN 61122 specifies physical requirements for the jacket and the magnetic disk, and magnetic
requirements for the magnetic disk.
BS EN 61122 provides guidance on the signal recording formats of analogue picture, time-compressed audio signals, digital data and control information recorded on the magnetic disk to ensure interchangeability of the recorded disk.
BS EN 61122 helps you improve the quality of still video floppy disk magnetic recording system.
