OPTICAL INFORMATION RECORDING MEDIUM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical information recording medium for eliminating necessity of an initializing process without re-designing a recording layer composition in the medium having a metastable Sb3Te phase belonging to a space group Fm3m in the medium having a phase change recording material having Sb and Te as a recording layer. SOLUTION: The optical information recording medium comprises the recording layer and a crystallization accelerating layer contacted with at least a part of the recording layer and made of a Bi compound having a high melting point.
