30、word ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical

31、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 international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in

32、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 given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare Internatio

33、nal Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of th

34、e 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 26925 was prepared by Ecma International (as ECMA-371) and was adopted, under a special “fast- track procedure”, by Joint Technical Commit

35、tee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. This second edition cancels and replaces the first edition (ISO/IEC 26925:2006), which has been technically revised. ISO/IEC 26925:2009(E) viii ISO/IEC 2009 All rights reservedIntroduction Ecm

36、a 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 toward the development of International Standards for 80 mm, 90 mm, 120 mm, 300 mm, and 356 mm

37、 media. 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. In February 2002, a group of companies proposed that TC31 develop a standard for 120 mm rewritable optical di

38、sks using phase change recording technology and based on ISO/IEC 16448 and ISO/IEC 16969. TC31 adopted this project and started the work that resulted in ISO/IEC 17341. In February 2005, a proposal was made to TC31 to develop a new Ecma Standard that supports high-speed recording of 120 mm and 80 mm

39、 rewritable disks based on the same technology as ISO/IEC 17341. This International Standard specifies two Types of rewritable optical disks: one (Type S) making use of recording on only a single side of the disk and yielding a nominal capacity of 4,7 Gbytes or 1,46 Gbytes per disk and the other (Ty

40、pe D) making use of recording on both sides of the disk and yielding a nominal capacity of 9,4 Gbytes or 2,92 Gbytes per disk. This International Standard, taken together with a standard for volume and file structure, such as for instance developed in Ecma Technical Committee TC15, provides the requ

41、irements for information interchange between systems. INTERNATIONAL STANDARD ISO/IEC 26925:2009(E) ISO/IEC 2009 All rights reserved 1 Information technology Data interchange on 120 mm and 80 mm optical disk using +RW HS format Capacity: 4,7 Gbytes and 1,46 Gbytes per side (recording speed 8X) 1 Scop

42、e 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 allo

43、wing 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 HS (High Speed). This International Standard also specifies 80 mm disks with capacities of 1,46 Gbytes and 2,92 Gbytes. T

44、hese 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 Claus

45、e 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, inc

46、luding 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 disk

47、s between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems. 2 Conformance 2.1 Optical disk A claim of conformance with this International Standard shall specify the Type implemented. An optical disk is

48、in conformance with this International Standard if it meets all mandatory requirements specified for its Type. 2.2 Generating system A generating system is in conformance with this International Standard if the optical disk it generates is in accordance with 2.1. ISO/IEC 26925:2009(E) 2 ISO/IEC 2009

49、 All rights reserved2.3 Receiving system A receiving system is in conformance with this International Standard if it is able to handle both Types of optical disk according to 2.1. 2.4 Compatibility statement A claim of conformance by a generating or receiving system with this International Standard shall include a statement listing any other standards supported. This statement shall specify the numbers of the standards, the optical disk types supported (where appropriate) and whether support includes reading only or bot
