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.

本发明涉及一种用于通过使用光,热或其它方式改变光学常数来记录,再现和擦除信息的光学信息记录介质,旨在提出一种新型组合物的记录膜材料,以实现更高的 信号传输速率。 具体地说,它是由铟(In)和A和B组成的合金(A是选自Ag,Cu和B中的至少一种元素是选自S,Se,Te中的至少一种元素),更特别地, 组成在上述三元素体系的化学计量化合物附近。 由于本发明的记录膜材料的结晶速度快,所以可以呈现能够应付信号传输速率较快的趋势的光信息记录介质。
