The Commiaee made major contributions to ISO/IEC/JTCl/SC23 for the development of 130 mm WORM Optical Disk Cartridges (ISO/IEC 9171) and of 130 mm Rewritable Optical Disk Cartridges using M.O. (ISO/IEC 10089). ECMA produced the camera-ready copies for these I

In addition ECMA published the following Standards: ECMA-130 (1988) ECMA-153 (1991) ECMA-154 (1991) ECMA-184 (1992) The first three of these ECMA Standards have been adopted under the fast-track procedure of ISO/IEC JTC1, as Intemational Standards ISO/IEC 10149, ISODC 11560 a
4、nd ISO/IEC 10090, respectively. Standard ECMA-184 and the present ECMA Standard have also been contributed to ISO/IEC for adoption under the fast- track procedure as Intemational Standards. They are the first of a series of ECMA Standards of different capacities, based on the optical disk cartridge
