Information processing -- Data interchange on 90 mm (3.5 in) flexible disk cartridges using modified frequency modulation recording at 7 958 ftprad on 80 tracks on each side -- Part 1: Dimensional, physical and magnetic characteristics
This standard was last reviewed and confirmed in 2007. Therefore this version remains current.
Provides the dimensional, physical and magnetic characteristics of the cartridge so as to provide physical interchangeability between data processing systems. Provides for full data interchangeability between data processing systems in conjunction with the ISO standards 8860-2 and 9293, and applies, moreover, in conjunction with ISO 683-13.
