適用范圍：This International Standard specifies a flexible disk cartridge drive and defines the necessary functional and electrical re-quirements (including logic signals) and the mechanical re-quirements of the interface for the connection of conforming flexible disk drives to a host system. It includes drives using media specified in many standards but does not exclude drives using other media.This International Standard is distinct from a specification in that it delineates a minimum set of requirements consistent with compatibility and interchangeability at the interface level. This standard is intended to facilitate the interconnection of flexible disk drives to a host system by a user who has available the technical capability to verify test performance up through the functional level. The user should also have the capability of specifying the overall system hardware and software that will be unique for this particular device, and should also have the capability of specifying the controller combination for the desired application and end use.This International Standard applies to both single- and double-sided disk drives using 200 mm (8 in) or 130 mm (5,25 in) envelope-size flexible disks. It does not prescribe the magnetic encoding or decoding method, the recording techniques, or the format used to write or read data. It does not apply to host/drive subsystems where there is no clear physical and functional separation between the host and its drive or drives. This standard, as originally developed, was written specifically for 200 mm and 130 mm flexible disk drives. However, the standard may be applied to other disk sizes. In particular, for smaller drive applications considering this standard it is recom-mended that smaller-size flexible disk drives and their con-trollers use the descriptions applicable to 130 mm flexible disk drives.
