<p>An optical recording medium 10 comprises a substrate 1, first protective layer 2, interfacial layer 3, recording layer 4, second protective layer 5, light absorbing and heat generating layer 6, third protective layer 7, reflection layer 8 and a protective film 9 laminated in order. The light absorbing and heat generating layer 6 is a metal layer or an alloy layer containing more than one element out of Ge, Sn, Pb, Cr, Ti, In, Si, Cd, Se, W, Mo, Zr, Nb, Zn and Hf, so that a reflectivity of the optical recording medium 10 and an optical modulation factor, which is an optical modulation factor in a phase changing state of crystalline or amorphous, in the recording layer 4 can be always maintained in high. Accordingly, a recording sensitivity of the recording layer 4 in the optical recording medium 10 can be increased without deteriorating a characteristic such as reflectivity and jitter. <IMAGE></p> |
