Optical information recording medium

摘要

For improving the jitter property and ensuring the high reliability of an optical disk, a metal film containing phosphorus is disposed in a reflective layer. The layer has a hardness of 60 mgf/mum² or more as nano indentation hardness, and an adhesive layer used for bonding has a glass transition temperature of 100° C. or higher but 200° C. or lower, an elastic modulus at 25 to 80° C. of 1000 MPa or more, and an adhesion strength of 4N or more. The dye for the dye recording layer has a water solubility of 20% or less as measured as light absorbance of hot water in which the dye recording layer is soaked.
