Abstract
A Phase Change Rewritable optical disk system with a high density of 0.57 μm/bit and high transfer rate up to 46.3 Mbps is presented. In this system, the Mark Edge Recording method is used to attain the total capacity of 19 GB in a double-sided 300 mm-diameter disk. Since this method requires precise recording mark length, a write compensation method, disk media and read data detection method suitable for a wide range of scanning linear velocities ranging from 10.7 to 27.4 m/s have been developed.
