This International Standard specifies the characteristics of a case for use with 120 mm DVD-RAM disks as specified in
ISO/IEC 16824. This International Standard specifies three related, but different implementations of such cases, viz.
Type 1 Provides a case for a one-sided (Type 1S) or a two-sided (Type 2S) DVD-RAM disk such that the disk can
not be removed from the case. This case is reversible.
Type 2 Provides a case for a one-sided DVD-RAM disk (Type 1S) such that the disk may be removed from the
case. This case is not reversible.
Type 3 Provides a case into which a one-sided DVD-RAM disk (Type 1S) may be inserted, then used as a
cartridge. This case is not reversible.
This International 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
This International Standard provides for mechanical interchange between optical disk drives. Together with 120 mm
DVD-RAM disks according to ISO/IEC 16824 and a standard for volume and file structure, it provides for full data
interchange between data processing systems.
