Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method capable of using even the inner peripheral part of a molding substrate as a signal area by reducing the distortion of the molding substrate in the vicinity of an inner hole. SOLUTION: The manufacturing method is used to manufacture an optical disk substrate by filling a cavity formed between a pair of metallic molds with a melted resin, making a cut punch protrude for forming an inner hole before the melted resin is cured and opening the metallic molds to take out a molding substrate after the melted resin is cured. Control is executed to switch the protruding pressure of the cut punch at least between two stages, and a low pressure is switched over to a high pressure before the curing of the melted resin. Alternatively, the cut punch is first stopped just before it reaches a surgical cutter, and then protruded again. Otherwise, an ejector pin is retreated in a direction away from the cavity in conjunction with the protruding operation of the cut punch, or an injection piston for supplying the resin is retreated.  Still otherwise, the holding pressure of the injection piston at the time of protruding the cut punch is made lower than a holding pressure in a step before or after the protruding step is performed.
