This standard specifies the characteristics of a case for use with the 120 mm and 80 mm DVD-RAM disks specified in ISO/IEC 17592. ISO/IEC 17594:2004 specifies nine related, but different implementations of this case.
This standard specifies:
the environments in which the cases are to be operated and stored;
the dimensional and mechanical characteristics of the case, so as to provide mechanical interchangeability between data processing systems.
This standard provides for mechanical interchange between optical disk drives. Together with ISO/IEC 17592 for 120 mm (4,7 Gbytes per side) and 80 mm (1,46 Gbytes per side) DVD-RAM disks and a standard for volume and file structure, it provides for full data interchange between data processing systems.
