ABSTRACT:
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):
