<P>PROBLEM TO BE SOLVED: To provide an optical recording medium which can reduce manufacturing costs while enhancing light resistance, and which can obtain a reproduced signal with a proper C/N ratio. <P>SOLUTION: This optical recording medium is equipped with a substrate 2, a light transmission layer 13, and a recording layer 12 formed between the substrate 2 and the layer 13; and the recording layer 12 comprises at least one kind of free metallic element selected from the group of Ni, Cu, Si, Ti, Ge, Zr, Nb, Mo, In, Sn, W, Pb, Bi, Zn and La, and an element, that is, S or O, which is bound with the metallic element contained in the recording layer 12 by the irradiation with a laser beam L for recording, so as to produce a crystal of a compound with the metallic element. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
