This International Standard specifies the mechanical@ physical and optical characteristics of an optical disk@ identified as DVD Rewritable Disk (DVD-RAM)@ to enable interchange 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 that differ only by their diameter of 120 mm and 80 mm@ and the resulting difference of capacity. This International Standard specifies - two related but different Types of this disk (see clause 7)@ - the conditions for conformance@ ?C 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@ ?C 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 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 disks between optical disk drives. Together with a standard for volume and file structure@ it provides for full data interchange between data processing systems. The optical disks specified by this International Standard may be enclosed in cases according to ISO/IEC 17594 as specified therein.
