摘要： Optical recording mediums are prepared by extrusion molding. In the extrusion molding, a thermoplastic resin heated to a given temperature is pressed between a roll stamper and a roll opposite thereto. A gap between the roll stamper and the roll is precisely defined by belt members fixed on each side of the roll where the roll does not come into touch with the thermoplastic resin. The joints of the respective belt members are formed at positions different from each other on the periphery of the roll. Alternatively the gap may be defined by cutting the roll substrate at a part on which the stamper member is fixed, or by interposing endless belts with a given thickness between the roll stamper and the roll. The stamper member provided on the roll stamper is reduced in stress, and has a surface precision of 10 .mu.m or less.

摘要： A process for manufacturing a substrate sheet for information recording mediums using a roll stamper including a flexible stamper member having a pattern corresponding to a preformat for an information recording medium, a first fixing member and a second fixing member integrally joined to both ends of the stamper member, and a pair of fit grooves capable of fittingly receiving the fixing members and formed in the periphery of a specular roll substrate in parallel to the axial direction of the specular roll substrate. The fixing members are fitted to the fit grooves so the stamper member is fixed along the periphery of the specular roll substrate between fit grooves. The first fixing member has a first member with a coefficient of linear expansion substantially equal to the coefficient of linear expansion of the stamper member and a second member having a larger coefficient of linear expansion than the coefficient of linear expansion of the first member. The first member is joined to the stamper member and the second member is positioned inside the first member with respect to the second fixing member. The roll stamper is set up to satisfy the relationship of expression (1):.DELTA.L.sub.1 -.DELTA.L.sub.2

摘要： A method for preparing a substrate sheet for an optical recording medium has the steps of controlling a roll stamper having a preformat pattern on the peripheral surface thereof and a molding roll disposed with a predetermined gap between the same and the roll stamper so that they have a predetermined temperature, feeding a thermoplastic resin heated to a predetermined temperature to the gap from a means for extruding the thermoplastic resin disposed on the upstream side of the gap, while the roll stamper and the molding roll are rotated at a predetermined rotational frequency, and then molding the thermoplastic resin into a sheet by pressing the resin between the roll stamper and the molding roll to transfer the preformat pattern to the resin. The method is characterized in that the molding is carried out under molding conditions regulated so that continuously measured gap temperatures of the substrate sheet may periodically fluctuate in a predetermined amplitude and so that the amplitude may accord with a previously set value of an amplitude corresponding to a desired transfer precision and birefringence value of the substrate sheet for the optical recording medium.
