摘要： 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.

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： 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.

摘要： A super-resolution optical recording medium has at least a recording layer and a super resolution layer on a substrate. In the recording layer, a minimum recording mark is formed with spaces within a beam spot of a laser beam in recording. The minimum recording mark has a size of a resolution limit of a reproduction optical system or less, and can be reproduced by the reproduction optical system due to the existence of the super solution layer. The minimum recording mark in an AFM image takes the shape of a convex arc on a leading edge thereof and the shape of a concave arc on a trailing edge thereof (the AFM image is a plan view which can be observed on a surface when the light transmission layer is removed), and spaces have the similar shape to these.

摘要： A method for recording information on an optical recording medium in which a laser beam modulated into one or a plurality of write pulses with one or a plurality of write powers in accordance with target data to be written is projected onto a recording layer of the optical recording medium to form a record mark. During recording the information on the optical recording medium, a data level and a weight index are assigned to each channel bit in reference data trains before and after the target data. Recording compensation of the target data is carried out in accordance with the sum totals of the products of the data level and the weight index in the reference data trains, so that it is possible to easily carry out high a real recording by writing fine mark/space trains.
