ABSTRACT:
A optical recording medium comprising a substrate having provided thereon a recording layer whose optical properties reversibly change on application of light or heat or a like means to conduct recording, reproduction, or erasing of information is disclosed, wherein said recording layer comprises a recording material mainly composed of Ge, Sb, Te and In, and is a mixture of Ge-Sb-Te and In.sub.1-x Te.sub.x wherein 0.4 <x<0.6. The optical recording medium achieves rewriting of information at a high speed and retains recorded information for a prolonged period of time medium whose optical properties change on irradiation with a condensed light beam, such as a laser beam, to conduct recording, reproduction or erasing of information. More particularly, it relates to an improved photo recording medium with which rewriting of information can be carried out at an increased speed and the recorded information can be maintained stably for an extended period of time.
