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： In a phase change optical recording medium, by determining heat conductivity relatively higher in one of interference layers on and under the recording layer, heat absorbed into the recording layer can be released moderately through an interference layer. Thereby, cross erasure caused by heating of adjacent tracks can be prevented, and at the same time, excessive heat radiation is prevented from a part of the recording layer nearer to the substrate to thereby maintain appropriate heat in the recording layer. As a result, cross-erasure is prevented, and data can be rewritten with the supply of typical recording/erasure power.
