METHOD AND APPARATUS FOR PRODUCING OPTICAL RECORDING MEDIUM

WIPO Patent Application WO/2007/058309

A2

Disclosed are a method and apparatus for producing an optical recording medium which comprises an intermediate layer having a good corrugated surface and only few defects at low cost. Specifically, a recording layer is formed on a substrate directly or via another layer, and a resin material layer is formed on the recording layer directly or via another layer. Then a stamper, which has a corrugated pattern for transfer corresponding to the corrugated surface to be formed, is placed on the resin material layer, and a bonded body is obtained by curing the resin material layer. After that, the stamper is separated from the resin material layer while heating the bonded body, thereby forming the resin material layer into an intermediate layer having a transferred corrugated pattern.
