Phạm vi áp dụng / Scope of standard

This standard specifies the general, physical, and magnetic requirements for interchangeability of the single-disk cartridge (top loading) as required to achieve unrecorded cartridge interchange between disk storages and associated information-processing systems. The single-disk cartridge (top loading), with two recording surfaces, is of the type intended specifically for use with digital recording and reproducing equipment employing access mechanisms capable of positioning up to 408 data tracks on each surface. The requirement for eight track areas on each recording surface for use as alternates in case of difficulty in reading or recording on any usable data tracks is identified.

The general, physical, and magnetic requirements for the single-disk cartridge specified in this standard include :

(1) Operating, storage, and test environments for the cartridge

(2) Physical dimensions of the cartridge and its components

(3) Materials and testing specifications, where necessary

(4) Magnetic recording and reproducing geometry, including track locations

(5) Magnetic surface and track quality test specifications and requirements

(6) Supporting diagrams, measurement methods, and appendixes to provide clarity and completeness of the standard
