发明名称 Optical information recording medium
摘要 An optical information recording medium for recording, retrieving and erasing mark length-modulated amorphous marks, which comprises a substrate (1), and a lower protective layer (2), a phase-change recording layer (3), an upper protective layer (4) and a reflective layer (5) having a thickness of from 40 to 300nm and a volume resistivity of from 20 to 150n OMEGA .m, formed in this sequence on the substrate/wherein the reflective layer (5) has a multilayer structure wherein at least 50% of the total thickness of the reflective layer is constituted by at least one layer of a thin metal film having a volume resistivity of from 20 to 150n OMEGA .m.
