METHOD AND APPARATUS FOR PRODUCING OPTICAL INFORMATION RECORDING MEDIUM, AND OPTICAL INFORMATION RECORDING MEDIUM

摘要

PURPOSE: A method and an apparatus for producing an optical information recording medium, and an optical information recording medium are provided to have a multi-layer structure, to easily manufacture a high-density optical disk having an information recording layer on a substrate having a thickness of 0.3 mm or less for which injection molding is impossible. CONSTITUTION: A resin stamper having, on a principal plane, asperity pits on which a thin film is formed and a second substrate having a thickness of 0.3 mm or less with radiation cured resin are bonded such that the asperity pits face to the second substrate(S1). The resin stamper is peeled off after the radiation cured resin is cured, thereby forming asperity pits on the second substrate(S2). A metal film is formed on the asperity pits on the second substrate to attain an information recording layer on the second substrate(S3). And a first substrate having an information recording layer and the second substrate having the formed information recording layer are bonded such that the both information recording layers face each other(S4).
