ABSTRACT:
An optical recording medium configured with a light reflection layer; a first protection layer; a recording layer containing a phase-change material which changes between crystalline and amorphous phases by a light irradiation; a second protection layer; and one of a cover layer and a protective coating layer disposed on a substrate in this order; and in which the light reflection layer is formed of one of an Al alloy and an Ag alloy; the first protection layer has a ZnS—SiO2mixture layer which contains a mixture of ZnS and SiO2, and a intermediate layer having higher thermal conductivity than the ZnS—SiO2mixture layer; the intermediate layer is formed on the side of the light reflection layer; the recording layer comprises Ge, Sb, and Te as main elements; and the second protection layer comprises a mixture of ZnS and SiO2.
