Specifications
It gives the physical mechanical and optical characteristic of 120 mm rewritable optical disks with capacities of 3,0 Gbytes and 6,0 Gbytes. The quality of the recorded and unrecorded signals the format of the data and the recording method are specified enabling information interchange. The data can be written overwritten and read many times using the phase change method. (These disks are identified as +RW).
