Specifies the general, physical, and magnetic requirements for interchangeability of the one- and two-sided 90-mm (3.5-in) (nominal) flexible disk cartridge (for 7958 bits-per-radian (bpr) use) as required to achieve unformatted disk cartridge interchange among disk drives using 80 tracks per side and associated information processing systems. Defines the requirements and supporting test methods necessary to ensure interchange at acceptable performance levels.
