光学信息记录介质及对光学信息记录介质的记录方法
摘要：
提供一种记录再现特性和耐腐蚀性优异的光学信息记录介质。为此，本发明的光学信息记录介质至少顺次具备：具有导向槽的基板(001)、反射层(002)、光吸收层(003)、反射侧保护层(004)、通过激光的照射光学特性会可逆地变化的记录层(006)、膜厚为50nm以下的光入射侧保护层(012)、树脂层(010)和被激光照射的透明基板(011)。光入射侧保护层(012)具有多个材料层，多个材料层中的最接近透明基板的光入射侧材料层(009)具有最小的内部应力。
摘要（英）：

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.
