适用范围: This International Standard specifies the physical and magnetic characteristics of magnetic tape cartridges, using magnetic tape12,65 mm wide so as to provide physical interchange of such cartridges between drives. It also specifies the quality of therecorded signals, the recording method and the recorded format, thereby allowing data interchange between drives by means ofsuch cartridges. The format supports variable length Logical Records, high speed search, and the use of a registered algorithmfor data compression.This International Standard specifies four types of cartridges depending on the length of tape contained in the case. These fourtypes are referred to as Type A, Type B, Type C and Type D; their nominal capacity is 100 Gbytes, 50 Gbytes, 30 Gbytes and10 Gbytes, respectively.NOTE - One Gbyte contains 1 000 000 000 bytes.Information interchange between systems also requires, at a minimum, agreement between the interchange parties upon theinterchange code(s) and the specification of the structure and labeling of the information on the interchanged cartridge.This International Standard shall be used only in conjunction with ISO/IEC 22091.Together with a standard for volume and file structure, e.g. Standard ISO 1001, this document provides for full datainterchange between data processing systems.
