    摘要： A rewritable optical information recording medium including a recording layer composed of an organic dye film is provided, in which recording and erasing information can be performed reversibly by laser light irradiation. A rewritable optical information recording medium including at least one organic dye film which is substantially made of only at least one kind of organic dye compounds as a recording film is provided. The recording and erasure of information are performed by a reversible physical change of the organic dye film substance caused by laser light irradiation. Specifically, data recording is performed by a physical change locally caused by the irradiation of recording laser light, data reproduction is performed by detecting change in intensity of returned light of reproducing laser light having less power than the recording laser light, and data erasure is performed by applying at least once continuous light or pulse light having laser power more than the reproducing laser light and less than the recording laser light. The physical change is a change in shape.

    摘要： An optical recording medium having two or more information recording layers in which information is recorded at a high recording density. The optical recording medium is comprised of information recording layers between a first surface at which light is incident and a second surface opposite the first surface. The first information recording layer nearest to the second surface is a phase-modulation information recording layer, and the second information recording layer is a reflectance-modulation information recording layer.

    摘要： A write once optical recording medium has an inorganic recording film which includes an oxide film having germanium oxide (GeO) as a principal component, and a metal film adjacent to the oxide film, the metal film having a titanium/silicon alloy (TiSi) as a principal component.
