This Standard specifies the dimensional, physical and magnetic characteristics of a 200 mm flexible disk cartridge using modified frequency modulation recording at 13 262 ftprad, 1.9 tpmm, on both sides. This Standard is identical with ISO 7065-1:1985.

This part of ISO 7065 specifies the dimensional, physical and magnetic characteristics of the cartridge, so as to provide physical interchangeability between data processing systems.NOTE - Numeric values in the SI and/or Imperial measurement systems in this International Standard may have been rounded and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should be neither intermixed nor reconverted. The original design was made using the Imperial measurement system.
