ABSTRACT:
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<.alpha..ltoreq.6, 3.ltoreq..beta..ltoreq.15, 50.ltoreq..gamma..ltoreq.65, 20.ltoreq..delta..ltoreq.35, 0.ltoreq..epsilon..ltoreq.5, provided that .alpha.+.beta.+.gamma.+.delta.+.epsilon.=100, and (2) having a recrystallization upper-limit linear speed in a range of 2.5 to 5.0 m/s. A recording method and a reproduction method, using this optical recording medium, are proposed.
