Scope and field of application

This International Standard specifies the general, physical, and magnetic characteristics and the pre-initialization for the physical interchange of 200 Mbytes magnetic twelve-disk packs, for use in electronic data processing systems.

NOTE - The original design of the subject of this International Standard was made using the Imperial measurement system. Some later developments, however, have been made using the SI measurement system. In the process of conversion into the alternative system, values may have been rounded. Therefore, they are consistent with but not exactly equal to each other. Either system may be used, but the two shall be neither mixed nor reconverted.
