摘要： A reliable magnetic recording medium manufacturing method is provided in which a resin material used for processing a recording layer into a concavo-convex pattern can be removed reliably. In the magnetic recording medium manufacturing method, an energy ray curable resin material is spread over a continuous recording layer. Then, a stamper having a predetermined concavo-convex pattern is brought into contact with the resin material to transfer the concavo-convex pattern to the resin material, and the resin material is irradiated with energy rays such that the irradiation energy on a portion excluding the edge portion of the resin material is greater than that on the edge portions. The curing reaction proceeds to a greater extent in the portion excluding the edge portions than in the edge portions. Then, the resin material is etched and removed such that more resin material is removed from the edge portions than from the other portion.

摘要： There is provided a stamper for imprinting on which a concave/convex pattern is formed with a plurality of convex parts of different widths protruding from a surface. In the concave/convex pattern, the respective convex parts are formed so that a distance between a top of a convex part and a reference plane defined in a range between the surface and a rear surface of the stamper is longer for convex parts with wide widths than for convex parts with narrow widths. An imprinting method transfers the concave/convex form of the stamper to a resin layer on the surface of a substrate. A method of manufacturing an information recording medium uses the concave/convex form transferred by the imprinting method to manufacture an information recording medium.

摘要： A method for manufacturing a magnetic recording medium with excellent production efficiency is provided in which the recording layer can be processed into a desired concavo-convex pattern with high precision and the resin layer can reliably and thoroughly be removed. A sub-mask layer having corrosion resistance against an oxygen-containing gas is provided over a main mask layer composed mainly of carbon. Furthermore, an intermediate mask layer is provided between the main mask layer and the sub-mask layer. The intermediate mask layer has corrosion resistance against the oxygen-containing gas, and its etching rate is higher for a halogen-containing gas than for the oxygen-containing gas. The resin layer removing step is conducted between the sub-mask layer processing step and the intermediate mask layer processing step (the main mask layer processing step). The resin layer removing step uses the oxygen-containing gas, and the intermediate mask layer processing step uses the halogen-containing gas.
