PURPOSE:To obtain an optical recording medium with good recording/ reproducing characteristics at high yield by providing such a material that has better peeling property for metal than the peeling property of a base layer material, on the recording layer side of the base layer. CONSTITUTION:Such a material that has better peeling property for metal than that of the base layer material is provided on the recording layer side of the base layer, that is, on the side which contacts to a metal stamper in the production process of the medium. This material having good peeling property reduces adhesion strength between the base layer 4 and the metal stamper and makes it easy to peel the produced replica from the stamper. As a result, the base layer is free from large peeling force during the peeling process and deformation of the preformat pattern 2 can be prevented. Also, the substrate 1 is free from large peeling force, which decreases generation of cracks in the substrate. The obtd. medium has good recording/reproducing characteristics with high productivity and high yield. |
