ABSTRACT:
A recording medium having at least a first inorganic material layer which overlies a predetermined substrate and which exhibits a light absorptivity for projected light, and a recording layer which overlies the first inorganic material layer and whose principal component is an organic material. The first inorganic material layer contains at least one element selected from the group consisting of In, Bi, Te, Sb, Ge, Sn, Pb, Cr, Nb, Ni, Pd, Fe, Pt, Re, Ta, Th, Ti, Zr and Tl and the content of the element or elements is at least 65 atomic-%.
Further, the first inorganic material layer may well be overlaid with a second inorganic material layer which exhibits a light transmissivity higher than that of this first inorganic material layer. Preferable as the material of the second inorganic material layer is an inorganic material which contains at least one element selected from the group consisting of In, Bi, Te, Sb, Pb, Ge and Sn and at least one element selected from the group consisting of S, Se and O.
In proximity to at least one surface of the first inorganic material layer, at least one stabilizing layer may be disposed as well.
