摘要：
The present invention aims at improving C/N, erasing ratio, modulation factor, recording sensitivity, and recording/erasing repeatability characteristics of a phase-change type optical recording medium.The recording layer of the optical recording medium is therefore formed of a chalcopyrite type compound having a composition represented by the formula:Au.sub..alpha. In.sub..beta. Sb.sub..gamma. Te.sub..delta.wherein0 atomic %
