    摘要: A method for producing a master disk 105 for an optical disk 110 includes a layer forming step of forming a heat-sensitive material layer 102 on a substrate 101, an exposure step of exposing the heat-sensitive material layer 102 partially to a laser beam, and a pit and land pattern forming step of forming a pattern of pits and lands by means of the difference between the etching rates of the exposed portion and the unexposed portion of the heat-sensitive material layer 102. The heat-sensitive material layer 102 includes at least Sb and O. When the composition ratio of O is defined as x (atom %), x is 3 or more and 50 or less.

    摘要: An object of the present invention is to provide a method for manufacturing an optical information recording medium and an optical information recording medium itself, forming a stacked layer with a uniform thickness, without being affected by a previously formed underlayer. An optical information recording medium having a light-transmitting layer includes a plurality of resin layers formed on at least one main surface 201a of a substrate 201. To solve the object, in the plurality of resin layers, an inside diameter of the (N+1)th (N≧1) resin layer, counted from the substrate is applied, is larger than that of the Nth resin layer. This method includes a plurality of spin coating methods for covering a center hole 202 of the substrate 201 by a cap, and then forming a resin layer on the substrate 201. The outside diameter of a cap 224 to cover the center hole 202 used for the (N+1)th (N≧1) spin coating process is larger than the outside diameter of a cap 214 used for the Nth spin coating process.

    摘要: A magnetron sputtering apparatus has a plurality of ring-shaped flat targets with different diameters disposed about one center axis. The apparatus includes magnets having the same polarity as each other and placed on both front surface side and rear surface side of each of the targets along an inner circumferential edge thereof, and magnets having the same polarity as each other and placed on both front surface side and rear surface side of each of the targets along an outer circumferential edge thereof. The magnets placed along the inner and outer circumferential edges are placed in such a way that the magnets along the inner circumferential edge and the magnets along the outer circumferential edge become opposite in polarity to each other.

    摘要: A method for the production of sintered powder metal preform employing a novel reduction step. As-water-atomized ferrous metal particles are coated by phenol resins by adding said phenol resins to said ferrous metal particles after heating the metal particles to about 130.degree. C. to 150.degree. C. Resin coated ferrous metal particles are then filled in a mold and compacted under high pressure to produce a compacted green preform sufficient to ensure adequate strength for handling after pressing. The green preform is then heated to a reduction temperature within the range of about 1100.degree. C. to 1250.degree. C. for a time sufficient to achieve reduction of said green preform.
