<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium having a recording film on which hole-making (recording) becomes possible by a relatively low laser power and which can obtain a furthermore better signal modulation degree while good recording characteristics are held. <P>SOLUTION: The optical information recording medium 10 has the recording film 4 on which a recording mark is formed by irradiation of energy beam on a substrate 1. This recording film 4 consists of a mixture of an In alloy and an oxide, and the hole-making (recording) becomes possible by the relatively low laser power on this recording film 4. The recording film which can obtain the furthermore better signal modulation degree while the good recording characteristics are held, is obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
