摘要: An object of the present invention is to provide an optical recording medium for high speed recording corresponding to 3× speed to 10× speed (10 m/s to 36 m/s) of DVD with a favorable recording sensitivity and overwriting performance (or characteristic). Therefore, the optical recording medium is characterized by providing on the transparent substrate at least a first protective layer, a phase-change recording layer having a maximum recording linear velocity of 10.0 m/s or more and is capable of being recorded at least at any one linear velocity of 10.0 m/s to 36.0 m/s, a second protective layer, a reflective layer having a thermal conductivity of 300 W/m·K or more and a layer of a low thermal conductivity material having a thermal conductivity of 7 W/m·K or less disposed between the second protective layer and the reflective layer with a thickness of 0.5 nm or more and 8.0 nm or less.
