摘要： A roll stamper for forming an information recording medium substrate has a stamper member having a pattern corresponding to a pre-format for an information recording medium formed in its obverse surface, fixation members fixed to both end portions of a reverse surface of the stamper so as to be integral with the stamper member, and fit grooves formed in a circumferential surface of a specular roll base parallel to the axis of the specular roll base. The fixation members are fitted in the fit grooves, and the stamper member is fixed on the circumferential surface of the specular roll base. The roll stamper also includes a mechanism for applying a tensile force to the stamper member. This roll stamper is used in an apparatus having an extruder for melting and extruding a resin to form a resin sheet and a specular roll facing the roll stamper to continuously form the information recording medium substrate.

摘要： A process for producing a resin molding having a concave-convex pattern on the surface includes the steps of providing an original die having a concave-convex pattern on the surface and a substrate having a flat surface, thereby counterposing the concave-convex pattern surface and the flat surface to each other through a spacer and forming a cell with a cavity formed by the original die, the substrate and the spacer; making an internal pressure of the cell cavity lower than an external pressure thereof, thereby filling at least one of a liquid polymerizable component and a liquid resin into the cavity due to a pressure difference between the external pressure and the internal pressure; curing at least one of the polymerizable component and the liquid resin in the cavity, thereby making a replica; and peeling the original die from the replica, thereby obtaining a resin molding.

摘要： An apparatus and method for manufacturing a substrate sheet for information recording mediums having a roll stamper consisting of a flexible stamper having a pattern corresponding to a preformat for an information recording medium, the flexible stamper being fixed along the corresponding periphery of a roll substrate. A roll is placed opposite the roll stamper. A molten-resin sheet wider than the flexible stamper member is formed. The apparatus has means for bringing the edges of a resin sheet into contact with the roll substrate before releasing the resin sheet from the roll stamper. The temperature is controlled, so that a temperature difference on the surfaces of edges of a resin sheet and a preformat pattern transfer area of the resin sheet is kept within 30.degree. C. when the resin sheet is separated from the roll stamper after the molten-resin sheet has been pressed between the roll stamper and roll.
