    摘要： There is provided a cast molding die for an information recording medium, having a mold surface with a prescribed unevenness pattern including a projection; wherein the projection has at least one pair of opposite side slopes each of which forms an acute angle with respect to the extension of the mold surface. By using the cast molding die having the above-mentioned projection with a three-dimensional shape, a defect such as lack in the resultant information recording medium is prevented.

    摘要： An optical recording medium wherein recording information has been recorded as pits, comprises an absorptive layer and a reflective layer placed thereon, the absorptive layer having, on the surface, concave portions thermally deformed by heat generated upon irradiation of light beams, and the reflective layer having concave pits formed by deformation as a consequence of the thermal deformation of the absorptive layer and covering said concave portions of the absorptive layer in such a state that the concave portions are not exposed.An optical recording method comprises irradiating an optical recording medium having an absorptive layer and a reflective layer placed thereon, with light beams to generate a heat, allowing the heat to cause the thermal deformation of the absortive layer to form concave portions on the surface of the absorptive layer, deforming the reflective layer as a consequence of the thermal deformation of the absorptive layer, thereby allowing the deformed reflective layer to cover the concave portions of the absorptive layer in such a state that the concave portions are not exposed and to form concave pits.

    摘要： A method produces a molding die for an information recording medium, having a mold surface with a prescribed unevenness pattern comprising a projection; the projection having different etching velocities along its projected thickness; and defining a pair of convergent opposite inclining side slopes. Each slope of the pair forms an acute inclining angle with respect to extension of the mold surface. A pattern-forming layer is formed comprising a common metal element throughout its thickness and an additional element differing in composition from the common metal element in the thickness direction of the pattern-forming layer. The common metal element and the additional elements have different etching velocities in the thickness direction of the pattern-forming layer. The pattern-forming layer is selectively etched with a common etchant to form the projection.

    摘要： A process for patterning a substrate by forming electrodeposited layers on the substrate so as to correspond with two or more kinds of patterns has the steps of preparing an electrodeposition original plate having conductive patterns respectively corresponding with patterns in which respective conductive patterns are laid bare and conductive patterns are insulated from each other in such a manner that the electrodeposited layers can be respectively independently formed on the conductive patterns successively, forming the electrodeposited layers on the respective conductive patterns and transferring the electrodeposited layers formed on the respective conductive patterns, to a substrate.
