摘要： A die for molding disc substrates, includes, in a stamper, a to-be-held surface that diverges continuously from an inner circumferential surface of a center hole. An inner stamper holder holding the inner circumferential side of the stamper includes a cylindrical body and a claw including a cavity forming surface substantially parallel to the inner circumferential side head surface, and a holding surface diverging tapered toward the cavity holding the to-be-held surface. In the cylindrical body portion, a cylindrical surface that is opposed to the inner circumferential surface of the stamper. The die prevents the claw of the inner stamper holder from projecting from a transfer surface of the stamper and solves a problem of insufficient strength of the inner circumferential side of the stamper.

摘要： A disc base molding method and apparatus are provided for the injection molding of disc bases so as to produce thin disc bases having increased signal transfer clarity with a shortened molding cycle. Upon closure of a mold, a signal is sent to a mold clamping start delay timer and an injection start delay timer. Pressure is increased for mold clamping at approximately the same time that molten resin is introduced into the mold cavity. The time period from the start of pressure increase when the molten resin is initially introduced to the mold cavity until a specific mold clamping force is reached, is controllable. Upon completion of the injection of the molten resin, the mold clamping force is maintained until the molten resin is solidified.
