适用范围：This International Standard specifies the characteristics of a case for use with the 120 mm and 80 mm DVDRAMdisks specified in International Standard ISO/IEC 17592. The present International Standard specifiesnine related , but different implementations of this case, viz.Type 1 A case for a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk such that thedisk cannot be removed from the case. This case is reversible.Type 2 A case for a one-sided (Type 1S) 120 mm DVD-RAM disk such that the disk may be removed fromthe case. This case is not reversible.Type 3 A case into which a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk may beinserted, then used as a cartridge. This case is not reversible.Type 4 A case for a two-sided (Type 2S) 120 mm DVD-RAM disk such that the disk may be removed fromthe case. This case is reversible.Type 5 A case into which a one-sided (Type 1S) or a two-sided (Type 2S) 120 mm DVD-RAM disk may beinserted, then used as a cartridge. This case is reversible.Type 6 A case for a two-sided (Type 2S) 80 mm DVD-RAM disk such that the disk may be removed fromthe case. This case is reversible.Type 7 A case for a one-sided (Type 1S) 80 mm DVD-RAM disk such that the disk may be removed fromthe case. This case is not reversible.Type 8 A case into which a two-sided (Type 2S) 80 mm DVD-RAM disk may be inserted, then used as acartridge. This case is reversible.Type 9 A case into which a one-sided (Type 1S) 80 mm DVD-RAM disk may be inserted, then used as acartridge. 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 mechanicalinterchangeability between data processing systems;This International Standard provides for mechanical interchange between optical disk drives. Together withInternational Standard 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 betweendata processing systems.
