Data interchange on 200 mm flexible disk cartridges using two-frequency recording at 13 262 ftprad on one side

2nd edition, January 1982

This Standard ECMA-54 specifies the mechanical, physical and magnetic characteristics of a 200 mm flexible disk cartridge recorded on one side to provide physical interchangeability between data processing systems. It also specifies the quality of the recorded signals, the track layout and the track format. Together with the labeling system specified in Standard ECMA-58, this track format affords for full data interchange between data processing systems.
