INFORMATION RECORDING MEDIUM, INITIALIZING METHOD FOR INFORMATION RECORDING MEDIUM AND RECORDING METHOD FOR INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a direct-read-after-write type disk capable of being easily initialized and stably forming an unalterable amorphous mark for a long period, the initializing method and the recording method. SOLUTION: A recording layer and a recording mark stabilizing layer in contact with the recording layer are provided on a substrate, a recording mark is formed by supplying energy and a part or all of the recording mark stabilizing layer in a recording mark area is diffused in the recording layer. Before forming the recording mark, the initializing process of crystallizing the recording layer by supplying the energy is executed.
