摘要： A roll stamper has a roll substrate and a stamper fixed thereto and having a convexity and concavity preformat pattern. The stamper has an auxiliary layer, including a material different from that of the stamper and a back surface on which the convexity and concavity preformat pattern is formed. The roll substrate has a low-melting layer on its surface and the auxiliary layer is in contact with the low-melting layer so that the stamper is fixed to the roll substrate.

摘要： A roll stamper for continuously preparing a substrate used for optical recording mediums, having a convexity and concavity preformat pattern, is prepared by a process comprising the steps of forming a low-melting metal layer on a roll substrate, and forming an auxiliary layer comprising a material different from that of a stamper, on the back of the stamper having on its surface a pattern corresponding with a convexity and concavity preformat pattern. The stamper is overlaid on the roll substrate in such a manner that the low-melting metal layer comes into contact with the auxiliary layer, and thereafter the low-melting metal layer is melted so that the stamper is fixed to the roll substrate.

摘要： An optical recording medium includes in sequence a transparent substrate, a light-reflecting layer, a transparent intermediate layer and a light-absorbing layer. The light-reflecting layer, the transparent intermediate layer and the light-absorbing layer in combination constitute a multi-layer optical element showing a high reflectance with respect to a reproducing light beam having a wavelength .lambda..sub.r. The resultant high reflectance state in the non-recorded region provides a high contrast in comparison with a record pit when the high reflectance multi-layer optical element is destroyed, and also provides the record with an improved resistance to degradation due to irradiation with the reproducing light beam.
