Document Type and Number:
Japanese Patent JPH02147388
Kind Code:
A
Abstract:
PURPOSE: To contrive higher C/N by providing a substrate and a recording film thereon comprising an Au-Te alloy, carbon and fluorine for recording information by irradiation with a laser light.
CONSTITUTION: An information recording medium 18 comprises a substrate and a recording film 14 provided thereon. The recording film 14 comprises an Au-Te alloy, carbon and fluorine, with the Au content being 2-47atom%.
