    • 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
    • 一种使用辊压机制造信息记录介质用基板的方法,所述辊压机包括具有与用于信息记录介质的预格式化相对应的图案的柔性压模构件,第一固定构件和与压模两端一体地连接的第二固定构件 以及一对能够适当地接收固定构件并且形成在与镜面辊基板的轴向平行的镜面辊基板周边的一对配合槽。 固定构件安装到配合槽,使得压模构件沿着镜面辊基板的周边固定在配合槽之间。 第一固定构件具有第一构件,其线性膨胀系数基本上等于压模构件的线性膨胀系数和具有比第一构件的线性膨胀系数更大的线性膨胀系数的第二构件。 第一构件连接到压模构件,第二构件相对于第二固定构件定位在第一构件的内部。 设置辊压机以满足表达式(1)的关系:DELTA L1- DELTA L2
