Method of producing optical recording medium by transfer process using a stamper, and optical recording medium produced thereby

摘要

A method for producing an optical recording medium of the present invention including a first laminating step, a second transferring step, a third detaching step, and a fourth forming step. The first step includes laminating a substrate and a transfer stamper with an uncured ultraviolet-curable resin interposed therebetween. The transfer stamper has recesses/projections that provide information to be transferred. The second step includes transferring the information to be transferred of the transfer stamper onto a surface of the ultraviolet-curable resin. The third step includes detaching the transfer stamper from the ultraviolet-curable resin at an interface therebetween after the ultraviolet-curable resin is cured. The fourth step includes forming a thin film layer on the information-transferred surface of the ultraviolet-curable resin. The thin film layer includes either a recording film or a reflection film. The method requires that either a weight of the transfer stamper or a viscosity of the ultraviolet-curable resin is set so that a surface roughness of the information-transferred surface of the ultraviolet-curable resin is smaller than a surface roughness of the surface of the transfer stamper on which the information to be transferred is provided.
