Optical recording medium and recording process utilizing the same. |
摘要 |
<p>An optical recording medium comprising a plastic substrate having a surface of minutely roughened structure and a thin metal film formed on the substrate is capable of strongly absorbing laser light of a specific wavelength region, thereby writing data on the medium. The optical recording medium is characterized in that the thin metal film comprises a metal of the platinum group and a second metal or semi-metal such that the thermal conductivity of the thin metal film is not higher than 80% of the thermal conductivity of the platinum group pure metal. The optical recording medium is, since jitter has been decreased, capable of a high-sensitivity and high-CNR recording.</p> |
