National bodi

36、es that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other i

37、nternational organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules gi

38、ven in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval

39、 by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 11976 was prepared by Ecma I

40、nternational (as ECMA-380) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. ISO/IEC 11976:2008(E) ISO/IEC 2008 All rights reserved ix Introduction Ecma Technic

41、al 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 JTC 1/SC 23 toward the development of International Standards for optical disks with a diameter of 80 m

42、m, 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 present Standard is the Second Generation of the UDO Standard initia

43、lly published (1 stEdition) as ECMA-350 in 2003 and as ISO/IEC 17345 in 2005. INTERNATIONAL STANDARD ISO/IEC 11976:2008(E) ISO/IEC 2008 All rights reserved 1 Information technology Data interchange on 130 mm rewritable and write-once-read-many ultra density optical (UDO) disk cartridges Capacity: 60

44、 Gbytes per cartridge Second generation Section 1 General 1 Scope This International Standard specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-optical Phase Change effects to enable data interchange between such disks. This

45、International Standard specifies two types of disk. Type RW (Rewritable) provides for data to be written, read and erased many times over the recording surfaces of the disk. Type WORM (Write Once Read Many) provides for data once written to be read a multiplicity of times. This type uses a Write Onc

46、e Read Many times recording material (written marks cannot be erased and attempted modifications of the written marks are detectable). Multisession (incremental write operations) recording may be performed on Type WORM disks. The disk is two-sided with a nominal capacity of 30,0 Gbytes per side and

47、the cartridge (two sides) provides a nominal capacity of 60,0 Gbytes. This International Standard specifies the following: the conditions for conformance testing and the Reference Drive; the environments in which the cartridges are to be operated and stored; the mechanical, physical and dimensional

48、characteristics of the cartridge so as to provide mechanical interchangeability between data processing systems; the format of the information on the disk, both embossed and user-written, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods

49、 used; the characteristics of the embossed information on the disk; the thermo-optical characteristics of the disk, enabling processing systems to write data onto the disk; the minimum quality of user-written data on the disk, enabling data processing systems to read data from the disk. This International Standard provides for interchange between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing sys
