摘要：
An optical recording medium capable of recording and erasing information, includes a first dielectric layer, a recording layer, a second dielectric layer, a light reflection and heat dissipation layer, and an overcoat layer which are successively overlaid on a substrate, the recording layer including a phase-change recording material which includes as constituent elements Ag, In, Sb, Te, and N and/or O with the respective atomic % thereof being .alpha., .beta., .gamma., .delta. and .epsilon. (the total atomic % of N and/or O), which are in the relationship of: 0
