    摘要: 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.

    摘要: An information memory apparatus includes an information storage medium having a thin film formed as a recording layer or a superresolution reading mask layer on a substrate directly or via a foundation layer to record and/or reproduce information stored in the form of an atom configuration change caused by irradiation of an energy beam. The information storage medium includes reflective layers as well. The information memory apparatus further includes a laser used for at least recording. The laser has a wavelength. The light absorptance of the recording layer or mask layer of the medium in a crystalline state at the wavelength is greater than or equal to the light absorptance of the recording layer or mask layer of the medium in an amorphous state at the wavelength. The information memory apparatus further includes an optical head control circuit, a tracking error detector, an optical head moving driver, a recording data modulator, a laser driver, a reproduced signal processor and a reproduced data sending unit.
