摘要： In an optical information recording medium with high-density having a thin light-transmitting layer, manufacturing time greatly lengthens when a light-transmitting layer is produced using a radiation curing resin. To solve the problem above, in a method of manufacturing an optical information recording medium, which forms a light-transmitting layer made of a radiation curing resin on a substrate having a signal recording layer, a liquid foundation is formed by coating the radiation curing resin in a first coating step. Next, a radiation curing resin is further coated on the foundation in a second coating step. After this, a curing step is performed. By separating the dropping and spreading of the radiation curing resin into two steps, not only the manufacturing time can be reduced, but also the volume of the used radiation curing resin can be reduced.

摘要： An optical disc manufacturing method suppresses thickness variation in intermediate layers disposed between any two data recording layers to achieve an intermediate layer of uniform thickness. A substrate having a center hole and data recording layer is first prepared. This center hole is then plugged with a capping member and a resin material is dripped from above the center hole while spinning the substrate around its center hole to coat the data recording layer with the resin by a spin coating method. The capping member is then removed. Then, a stamper having a groove or lands and pits on its surface is prepared. The groove or lands and pits side of the stamper is then pressed into the resin material on the substrate, and the resin is then cured to form an intermediate layer. The stamper is then separated from the substrate to leave a data recording layer in the surface of the intermediate layer with a groove or land-and-pit pattern corresponding to the groove or lands and pits in the stamper.

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.
