OPTICAL INFORMATION RECORDING MEDIUM AND METHOD FOR RECORDING IN OPTICAL INFORMATION RECORDING MEDIUM

摘要

An optical information recording medium having excellent recording/reproducing characteristics and corrosion resistance. The optical information recording medium is at least successively provided with a substrate (001) having a guide groove; a reflecting layer (002); a light absorbing layer (003); a reflection side protecting layer (004); a recording layer (006) wherein optical characteristics reversibly change by laser beam irradiation; a light incoming side protecting layer (012) having a film thickness of 50nm or less; a resin layer (010); and a transparent substrate (011) whereupon the laser is applied. The light incoming side protecting layer (012) has a plurality of material layers, and among the material layers, a light incoming side material layer (009) closest to the transparent substrate has the least internal stress.
