发明名称 MULTILAYER INFORMATION RECORDING MEDIUM AND PROCESS FOR PRODUCING THE SAME
摘要 <p>A process for producing a multilayer information recording medium comprising steps for forming a thin film layer on the information surface of a substrate having the information surface, for mounting a UV-curing resin film and a light transmitting resin stamper on the thin film layer and pressing them, for curing the UV-curing resin film by transmitting the light transmitting resin stamper with light and forming the information surface by stripping the light transmitting resin stamper from the UV-curing resin film thus cured, and for forming an information layer by coating the information surface with the thin film layer, characterized in that a transfer surface for forming the light transmitting resin stamper information surface is provided and a metal thin film is formed on the transfer surface. When a multilayer information recording medium is produced by the inventive process, the production process can be simplified and production costs can be reduced because new information layers can be formed continuously and sequentially from the same surface side. Furthermore, only the stamper can be stripped from a cured UV-curing resin film easily with a relatively small force because a thin film layer is formed on the surface of the stamper, and therefore a multilayer information recording medium having a high dimensional accuracy can be obtained without causing any stripping of other layers.</p>
