3、f History ECMA Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC JTC1/SC23 toward the development of International Standards for optical disks wit
4、h a diameter of 80 mm, 90 mm, 120 mm, 130 mm, 300 mm and 356 mm. Numerous standards have been developed by TC31 and published by ECMA, almost all of which have also been adopted by ISO/IEC under the fast-track procedure as International Standards. The following ECMA Standards for DVD 120 mm and 80 m

7、ten members of the DVD Forum proposed to TC31 to develop a standard for 120 mm DVD Re-recordable optical disks using Phase Change recording technology. TC31 adopted this project and started the work that has resulted in this ECMA Standard. This ECMA Standard specifies two Types of Re-recordable opti
