Standardization of Optical Disk Cartridges since 1984

Second Programme of Work of TC31, 1992-1996

The second programme of work adopted by TC31 comprises the development of

• further 130 mm ODCs for different applications,
• one standard for a 130 mm ODC of the WORM type,
• further 90 mm ODCs for different applications,
• two standards for 300 mm ODCs of the WORM type,
• one standard for a 120 mm ODC for different applications.

As a result TC31 produced seven standards, four for 130 mm ODCs and three for 90 mm ODCs, specifying a single format of the CCS type:

• ECMA-183, ECMA-184, ECMA-195, ECMA-238 (WORM),
• ECMA-201, ECMA-223, ECMA-239

In addition two standards for 300 mm were produced, and one standard for 120 mm:

• ECMA-189 for the SSF Method
• ECMA-190 for the CCS Method
• ECMA-240 for CD with PD format.

ECMA-183, ECMA-184 and ECMA-201 have been adopted by ISO/IEC JTC 1 under the fast-track procedure as International Standards ISO/IEC 13481, ISO/IEC 13549 and ISO/IEC 13963, resp.

ECMA-195 has been used by SC 23 as basis for ISO/IEC 13842. The second edition of ECMA-195 is identical with this International Standard.

ECMA-238, ECMA-239 and ECMA-240 have been adopted by ISO/IEC JTC 1 under the fast-track procedure as International Standards ISO/IEC 15486, ISO/IEC 15498 and ISO/IEC 15485, resp. ECMA-238 is based on ISO/IEC 14517.

ECMA-189 and ECMA-190 have been used by SC 23 as basis for ISO/IEC 13614 and ISO/IEC 13403 resp.
