CAN/CSA-ISO/IEC 17594-05 (R2015)

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). At the time of publication, ISO/IEC 17594:2004 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC. 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.
