ABSTRACT:
An optical recording medium capable of recording, rewriting and erasing information utilizing changes in optical properties is disclosed, which comprises a substrate having thereon a layer of a recording material that changes reversibly in optical properties thereof upon irradiation with light or application of heat, wherein the recording material consists essentially of at least one element of Group Vb of the periodic table selected from the group consisting of As, Sb, and Bi and at least one element of Group VIb of the periodic table selected from the group consisting of S, Se, and Te; and has a composition corresponding to that of a mixture of at least two stoichiometric compounds represented by the chemical formula Vb-hd 2Vib.sub.3 ; and contains at least one of Se and Te.
