CAN/CSA-ISO/IEC 17341:10 (R2020) ✓ Most Recent

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).

This Standard supersedes CAN/CSA-ISO/IEC 17341-07 (adoption of ISO/IEC 17341:2006, third edition, 2006-12-01). At the time of publication, ISO/IEC 17341:2009 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 mechanical, physical and optical characteristics of 120 mm rewritable optical disks with capacities of 4,7 Gbytes and 9,4 Gbytes. It specifies the quality of the recorded and unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase change method. These disks are identified as +RW.

This International Standard also specifies 80 mm disks with capacities of 1,46 Gbytes and 2,92 Gbytes. These disks have the same characteristics as the 120 mm disks, except for some parameters related to the smaller dimensions. All parameters unique for the 80 mm disks are specified in Annex A.

This International Standard specifies the following:

• two related but different Types of this disk (see Clause 7);
• the conditions for conformance;
• the environments in which the disk is to be tested, operated and stored;
• the mechanical, physical and dimensional characteristics of the disk, so as to provide mechanical interchange between data processing systems;
• the format of the information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method;
• the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk.

This International Standard provides for the interchange of disks between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems. See more
