摘要： This invention, related to an optical information recording medium for recording, reproducing and erasing information by causing changes in the optical constant by using light, heat or other means, is intended to propose a recording film material of a novel composition in order to realize higher transfer rate of signals. Specifically, it is an alloy composed of indium (In) and A and B (A is at least one element selected from Ag, Cu, and B is at least one element selected from S, Se, Te), and more particularly it is composed in the vicinity of the stoichiometric compound of the above three-element system.Since the recording film material of this invention is fast in the rate of crystallization, it is possible to present an optical information recording medium that can cope with the forthcoming trend of higher transfer rate of signals.

摘要： Phase-change type, reversible optical information recording medium, being possible for recording, reproducing, erasing, and rewriting of information, by use of a laser beam. This invention consists of recording thin film of ternary elements, for example, containing Ge, Te, Sb/or Bi or quaternary elements containing the fourth element of Se with which a part of Te is replaced, which is established on such surface-flat substrates as glass or plastics. In this case, the component ratio of Te and Se is selected not to be excess for other elements, such as Ge, Sb/or Bi so as to be fixed as stable compounds of stoichiometric compositions of GeTe, Sb.sub.2 Te.sub.3 /or Bi.sub.2 Te.sub.3, or GeSe, Sb.sub.2 Se.sub.3 /Bi.sub.2 Se.sub.3 when crystallized. Strictly speaking, a concentration of each component is selected to have proper ratio of the number of atomes each other so as to represent whole composition as the sum of each component. By this treatment, it is possible to have high crystallization speed and long cyclability of recording/erasing. The effect of Se is to increase the viscosity of the system and to make easily to obtain amorphous state; and moreover, by selecting of proper amount displaced with Te, it is possible to obtain the composition of recoding film superior in both characteristics of recording (amorphization) and erasing (crystallization).
