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.

The stamper is used a plurality of times to repeat these steps a plurality of times, thereby manufacturing a plurality of information recording media.

From among the plurality of information layers, the information layer excluding the information layer arranged closest to the substrate and the information layer adjacent to the information layer closest to the substrate has asymmetrical reflection characteristics in which reflectance on the substrate side when light incident from the substrate side is reflected on the information layer toward the substrate side is lower than the reflectance on the cover layer side when light incident from the cover layer side is reflected on the information layer toward the cover layer side.

摘要： An optical recording medium includes a support substrate, and a light transmission layer 12 that is disposed so as to come in contact with the support substrate. At least one of a refractive index of the support substrate and a refractive index of the light transmission layer, and an extinction coefficient of the support substrate and an extinction coefficient of the light transmission layer is different. As such, according to the invention, a reflective layer is not formed between the support substrate and the light transmission layer, such that the support substrate and the light transmission layer directly come in contact with each other. Accordingly, since at least one of the refractive index and the extinction coefficient is different, reflection occurs at the interface between the support substrate and the light transmission layer. Therefore, data held by a plurality of pits, that are arranged on the support substrate in a spiral shape or a concentric shape, can be correctly read out.
