摘要：
A mold for molding a plurality of substrates for an information recording medium includes a fixing member, a plurality of units fixed to the fixing member, and a molding cavity. Each of the units has a preformat pattern with a surface corresponding to information recording medium formed on its surface, and the molding cavity is disposed opposite to the units so that the preformat patterns face the molding cavity.
