Filed: 1985-06-12
Abstract: PURPOSE:To provide an information recording member having excellent reliability and enabled in recording, in an optical information recording member obtained by forming an information recording medium to a substrate, by containing two elements of Se and Sb in the information recording medium and setting Sb to a specific atomic % range. CONSTITUTION:In an optical information recording medium constituted by containing two elements of Sb and Se, the content of Sb to Se is set to 50-90 atomic % in order to obtain not only sufficient light absorption when semiconductive laser (wavelength; 830nm) is used as laser but also the large change in optical characteristics by heating. A substrate 2 comprises PMMA. The optical recording medium 3 is obtained by a method wherein Sb2Se3 and Sb are separately received in vapor deposition boats and, after a vacuum degree has been set to 5X10<-4>Pa, a current is made to flow to the vapor deposition boats simultaneously to perform vapor deposition. Because a composition varies at the time of the vapor deposition of Sb2Se3, the vapor deposition rate of Sb is controlled to make the mixing ratio of Sb-Se constant. The obtained composition consists of 60% of Sb and 40% of Se on an atomic % basis and a film thickness is 100nm.
