2、m Optical Disk using +R Format Capacity: 4,7 and 1,46 Gbytes per Side (Recording speed up to 16X) Standard ECMA-349 4thEdition - June 2008 . Introduction Ecma Technical Committee TC31 was established in 1984 for the standardization of Optical Disks and Optical Disk Cartridges (ODC). Since its establ
3、ishment, 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 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 f
4、ast-track procedure as International Standards. In April 2003 a group of Companies proposed to TC31 to develop a standard for 120 mm recordable optical disks using the WORM recording technology and based on the DVD Read-Only standard (ECMA-267) and the +RW format (ECMA-337). TC31 adopted this projec
5、t and started the work that has resulted in the first edition of ECMA-349. This Ecma Standard specifies two Types of recordable 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 or 1,46 Gbytes per disk and the other (Type D)
6、making use of recording on both sides of the disk and yielding a nominal capacity of 9,4 or 2,92 Gbytes per disk. In December 2003 a proposal was made to TC31 to update this Ecma Standard for recording speeds up to 8 times the Reference velocity. TC31 adopted this project which has resulted in the s
7、econd edition of ECMA-349. In February 2005 a proposal was made to TC31 to update this Ecma Standard for recording speeds up to 16 times the Reference velocity and to facilitate the application of the Video Content Protection System. This Ecma Standard, taken together with a standard for volume and
8、file structure, such as for instance developed in Ecma Technical Committee TC15, provides the requirements for information interchange between systems. This Ecma Standard has been adopted by the General Assembly of June 2008. - i - Table of contents Section 1 General 1 1 Scope 1 2 Conformance 1 2.1

35、 physical and optical characteristics of 120 mm recordable 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 allowing for information interchange by means of such disks
36、. The data can be written once and read many times using a non-reversible method. These disks are identified as +R. This Ecma Standard also specifies 80 mm disks with capacities of 1,46 Gbytes and 2,92 Gbytes. These disks shall have the same characteristics as the 120 mm disks, except for some param
37、eters related to the smaller dimensions. All parameters unique for the 80 mm disks are specified in Annex A. 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 stor
38、ed, 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, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method
39、, the characteristics 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 int
