An information recording medium manufacturing method is provided in which a resin material can be reliably cured even when a light-transmitting stamper is used repeatedly. A resin mask forming method and a transferring apparatus and a light-transmitting stamper used in these methods are also provided. In the above methods, a visible light curable resin material is spread over a workpiece. Then, a light-transmitting stamper including a transferring portion having a predetermined concavo-convex pattern formed therein is brought into contact with the resin material to transfer the concavo-convex pattern to the resin material, and light including visible light is projected onto the resin material through the light-transmitting stamper to cure the resin material.

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.

A magnetic recording medium is provided, which has recording layers having concavo-convex patterns formed on both sides of a substrate and can easily distinguish one face from the other face. A magnetic recording and reproducing apparatus having the magnetic recording medium is also provided. The magnetic recording medium includes a substrate, a first recording layer formed in a first concavo-convex pattern on a side of a first face, and a second recording layer formed in a second concavo-convex pattern on a side of a second face. The magnetic recording medium also includes a distinction element which can distinguish the first face from the second face. At least part of the distinction element is disposed in a non-recording area adjacent to at least one of an inner part and an outer part of a recording area in a radial direction.

A method for manufacturing an information recording medium, a method of transferring a concavo-convex pattern, and a transfer apparatus are provided which are capable of curing a resin material with reliability even when using a light-transmitting stamper repeatedly. A stamper made of a light-transmitting resin, having a predetermined concavo-convex pattern formed on its transfer area, is inspected for an optical characteristic. The stamper is brought into contact with an energy-ray curable resin material applied to an object to be processed, thereby transferring the concavo-convex pattern to the resin material, and the resin material is irradiated with an energy ray through the stamper so that the resin material cures. The stamper is used a plurality of times to repeat these steps a plurality of times, thereby manufacturing a plurality of information recording media.

An imprinting method which is capable of forming a concave/convex pattern in a short time without causing deformation or incompleteness of the pattern. In the imprinting method, a stamper-pressing step of pressing a stamper against a resin layer formed by applying a resin material to a surface of a substrate, in a state of the resin layer being heated to a predetermined temperature, and a stamper-removing step of removing the stamper from the resin layer while maintaining either of the state of the resin layer being heated and a state of the temperature of the heated resin layer being held, are performed in the mentioned order, whereby shapes of recesses/protrusions of the stamper are transferred to the resin layer to form a concave/convex pattern on the substrate.
