The object of the present invention is to decrease these defects. A method for manufacturing a stamper comprises performing a plasma surface treatment on a surface of a father stamper 106 having patterns of pits and lands, forming a nickel electroformed film (II) 107 on the surface of the father stamper 106, and separating the nickel electroformed film (II) 107 from the father stamper 106 so as to form a mother stamper 108.

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.

摘要： A method for manufacturing an optical disk master includes: forming a resist layer by the application of a chemically amplified resist; converting an information signal into a multipulse signal having a symmetrical shape; exposing the resist layer in accordance with the multipulse signal; heat-treating the resist layer; and developing the resist layer to form signal pits. The signal pits are exposed to the multipulse signal, which is obtained by dividing a pulse into symmetrical pulses, thereby adjusting the exposure area and achieving a desired pit shape.
