CAN/CSA-ISO/IEC 17594:05 (R2010)

This National Standard of Canada is equivalent to International Standard ISO/IEC 17594:2004. 1 Scope This International Standard specifies the characteristics of a case for use with the 120 mm and 80 mm DVDRAM disks specified in International Standard ISO/IEC 17592. The present International Standard specifies nine 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 the disk 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 from the 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 be inserted, 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 from the 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 be inserted, 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 from the 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 from the 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 a cartridge. 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 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 processing systems; This International Standard provides for mechanical interchange between optical disk drives. Together with International 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 between data processing systems.
