2、 Geneva T/F: +41 22 849 6000/01 www.ecma-international.org . Brief 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 toward the devel

3、opment of International Standards for 80 mm, 90 mm, 120 mm, 130 mm, 300 mm, and 356 mm media. Numerous standards have been adopted by ISO/IEC under the fast-track procedure as International Standards In February 1997 a group of ten Companies, known as the DVD Forum, proposed to TC31 to develop stand

4、ards for optical disks known as DVD disks. TC31 accepted this proposal and started the work that has led to two Ecma Standards that were eventually adopted by ISO/IEC as International Standards under the fast-track procedure. ECMA-267 (1997) 120 mm DVD-Read-Only Disk ISO/IEC 16448 ECMA-268 (1997) 80

5、 mm DVD-Read-Only Disk ISO/IEC 16449 Further work, supported by nine members of the DVD Forum, has been undertaken for a rewritable disk known as DVD-RAM, has led to further Ecma and ISO/IEC Standards. ECMA-272 (1998) 120 mm DVD Rewritable Disk (DVD-RAM) ISO/IEC 16824 ECMA-273 (1998) Case for 120 mm

6、 DVD-RAM Disks ISO/IEC 16825 ECMA-331 (2001) Case for 120 mm and 80 mm DVD-RAM Disks ISO/IEC 17594 This Standard ECMA-330 constitutes a further development of Standard ECMA-272 proposed to, and accepted by, Ecma/TC31 on presentation by Toshiba Corporation on behalf of ten other Member Companies of t

7、he DVD Forum. It specifies two Types of rewritable optical disks with a nominal capacity of 4,7 Gbytes and 9,4 Gbytes. Apart of the larger capacity, these disks present considerable performance improvements over those of the disk according to Standard ECMA-272. In addition a new defect management al

8、lows real time recording. Compared to the 2ndEdition of Standard ECMA-330 (published by Ecma in June 2002), this 3rdEdition incorporates few changes in order to achieve complete alignment with International Standard ISO/IEC 17592:2004(E). This Ecma Standard has been adopted by the General Assembly o

32、hange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase change method. Two Types are specified

33、 that differ only by their diameter of 120 mm and 80 mm, and the resulting difference of capacity. This Ecma Standard specifies two related but different Types of this disk (see clause 7), the conditions for conformance, the environments in which the disk is to be tested, operated and stored, the me

34、chanical, 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, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method, the char

35、acteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk. This Ecma Standard provides for the interchange of disks between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange b

36、etween data processing systems. The optical disks specified by this Ecma Standard may be enclosed in cases according to Standard ECMA-331 as specified therein. 2 Conformance 2.1 Optical Disk A claim of conformance with this Ecma Standard shall specify the Type implemented. An optical disk shall be i

37、n conformance with this Ecma Standard if it meets all mandatory requirements specified for this Type. 2.2 Generating system A generating system shall be in conformance with this Ecma Standard if the optical disk it generates is in accordance with 2.1. 2.3 Receiving system A receiving system shall be

38、 in conformance with this Ecma Standard if it is able to handle both Types of optical disk according to 2.1. 3 References The following standards contain provisions which, through reference in this text, constitute provisions of this Ecma Standard.

46、 of polarization of an optical beam is the direction of the electric vector of the beam. NOTE The plane of polarization is the plane containing the electric vector and the direction of propagation of the beam. The polarization is right-handed when to an observer looking in the direction of propagati

47、on of the beam, the end-point of the electric vector would appear to describe an ellipse in the clockwise sense. - 2 - 4.12 Recording layer A layer of the disk on, or in, which data is written during manufacture and/or use. 4.13 Sector The smallest addressable part of a track in the Information Zone

48、 of a disk that can be accessed independently of other addressable parts. 4.14 Space A feature of the recording layer which may take the form of a crystalline domain, a non-pit or any other type or form that can be sensed by the optical system. The pattern of marks and spaces represents the data on

49、the disk. 4.15 Substrate A transparent layer of the disk, provided for mechanical support of the recorded layer(s), through which the optical beam can access a recording layer. 4.16 Track A 360 turn of a continuous spiral. 4.17 Track pitch The distance between centrelines of adjacent tracks (a groove and a land), measured in a radial direction. 4.18 ZCLV A disk format requiring Zoned Constant Linear Velocity operations. 4.19 Zone An annular area of the disk. 5 Conventions and notations 5.1 Representation of numbers A measured value is rounded off to the least significant di
