    摘要: An optical recording medium comprises a superresolution film which has a light transmittance varying in accordance with the intensity of incident light and which has a superresolution function for optically masking part of incident light to form an optical aperture having a smaller size than a spot size of incident light, the superresolution film including at least two kinds of superresolution films having different response times until the superresolution function occurs after being irradiated with light. Thus, it is possible to easily and surely reduce the light spot size to greatly enhance the recording density. In addition, it is possible to extend the operating wavelength range by providing at least two kinds of superresolution films having different operating wavelengths causing the superresolution function.

    摘要: An optical disk which operates which two of more different wavelengths, comprising a disk substrate on which tracks are formed at a track pitch of not more than 0.5 &mgr;m corresponding to light with a short wavelength, a super-resolution film whose transmittance changes due to irradiation of light, and a recording layer, wherein the transmittance of the super-resolution film changes due to the irradiation of light with a long wavelength. In this optical disk, information recorded by light with a short wavelength can be reproduced by light with a long wavelength.
