Patent ID: 7193960

Claim:
A method of manufacturing an optical recording medium having a second recording layer, a space layer, a first recording layer, and a light transmitting layer, on a supporting substrate, including the steps of: (A) providing a radiation-curable resin layer backed with a lining sheet on a stamper for the formation of information pits and/or grooves for the first recording layer, irradiating the resin layer with radiation to cure the resin layer, and then removing the stamper, thereby to form the light transmitting layer supported by the lining sheet; (B) forming the first recording layer on the light transmitting layer; (C) forming the second recording layer on the supporting substrate with information pits and/or grooves for the second recording layer formed; (D) laminating the lining sheet with the light transmitting layer and the first recording layer formed and the supporting substrate with the second recording layer formed via the space layer so that the first recording layer and the second recording layer are located inside; and (E) removing the lining sheet, wherein the step (A) includes forming the radiation-curable resin layer on the stamper and superposing the lining sheet on the resin layer, thereby to provide the radiation-curable resin layer backed with the lining sheet and irradiating the resin layer with radiation to cure the resin layer.
