    摘要: An optical data recording medium, in which irradiation of a light beam is used for recording and/or reproducing data includes (i) a substrate having an a rise and/or a recess which are a light-incident surface, (ii) a reflective layer, provided on the light-incident surface of the substrate, for reflecting the light beam, (iii) a light absorption layer for converting, to heat, a light of the light beam to heat on the surface of the reflective layer, (iv) a reproducing layer, provided on the surface of the heat-light converting layer, having a transmittance that changes in accordance with a light intensity distribution of the light beam. The optical data recording medium is excellent in super-resolution property, and enables reproduction of a shorter mark length.

    摘要: An optical information recording medium of the present invention includes a thin film section made up of one or more thin film, the thin film section being provided on a substrate. Thin films of the thin film section include a single optical multiple interference film which incites optical multiple interference in a thin film section, the optical multiple interference being incited by the change of complex refractive index in accordance with the intensity of incident light. Also, the composition and thickness of the optical multiple interference film are arranged in such a manner as to cause the wavelength distribution of the reflectance of the thin film section at room temperatures to have a minimum value within wavelengths of ±80 nm of the incident light for reproduction. With this, the design freedom of the optical multiple interference film which realizes super-resolution reproduction with a reduced effective reproduction spot is significantly increased.
