Abstract:
1. A method for manufacturing an information recording medium including N information layers (where N is an integer of 3 or more), (N−1) intermediate layers interposed between the information layers and a protective layer laminated on the Nth information layer which are placed on a substrate formed with a first reference point, comprising: a process of forming the information layer on the substrate; a process of repeating, (N−1) times, a process of applying radiation curable resin on the information layer, a process of affixing a transfer stamper formed with a second reference point to the radiation curable resin, a process of curing the radiation curable resin by irradiation, and a process of forming the intermediate layer by peeling the transfer stamper at an interface with the radiation curable resin, in order to sequentially form the (N−1) information layers and the (N−1) intermediate layers and thereafter form the Nth information layer; and a process of forming the protective layer on the Nth information layer, wherein in the process of affixing the transfer stamper to the radiation curable resin, the transfer stamper is affixed so that the second reference point of the transfer stamper is each time at a different position with respect to the first reference point of the substrate.
