PURPOSE:To make possible the manufacture of a recording film which demonstrates high oxidation resistance, long life and high sensitivity even at high temperature and humidity by forming a recording film, containing (Cu, Te100-x)ySez(2<=x<=40 atomic %, 80<=y<=95 atomic %, 5<=z<=20 atomic %) alloy as well as carbon and hydrogen, where information is recorded by projecting laser beam to the surface of a substrate. CONSTITUTION:An information recording medium 18 consists of a substrate 13 and many recording films 14 laminated on the substrate 13. The substrate 13 used is made of a transparent material for a laser beam projected to an information recording medium 18 for recording and retrieving information. The recording film 14 containing (Cu, Te100-z)ySez(2<=x<=40 atomic %, 80<=y<=95 atomic %, 5<=z<=20 atomic %) alloy as well as carbon and hydrogen is a binary intermetallic compound of Cu-Te. Cu27 and Te73 showing an eutectic point fuse at less than 330 deg.C or a temperature lower than Te. The composition of Cu should range from 2 to 40atomic %, considering the fusion point. The composition of Se should range within the limits of 5<=z<=20. |
