Abstract: An optical disk molding apparatus and method are provided which prevent data formed on a molded object from being damaged and prevent quality deterioration of the molded object. There are provided a mold moving device, a first gas supply device, and a controller, whereby a first release space part is formed by opening molds from a mold clamp state by a movement distance not damaging a data transferred face of the optical disk, and a gas is supplied to the first release space part at a point in time when the first release space part is formed, thereby totally separating the optical disk and a stamper from each other. No damage is caused to a data transferred face at the point in time when the first release space part is formed. Since separation between the optical disk and the stamper is performed via pressure of the gas after the first release space part is formed, data is prevented from being damaged over the data transferred face of the optical disk in its entirety.

Abstract: An injection-compression molding apparatus includes a stationary mold provided with a nozzle for injecting molten resin, and a movable mold driven by a servo motor. In compressing the resin, high-speed position control of the movable mold is first performed, which is then switched to speed feedback control which enables delicate regulation of clamping pressure in accordance with pressure fluctuations in the resin.

Abstract: A stamper protecting layer is interposed between a mold and a stamper of an optical disk molding apparatus, so that forces generated by extension and shrinkage of the stamper relative in a diametrical direction of the stamper to the mold when an optical disk is molded are absorbed by the stamper protecting layer, with this arrangement, the stamper is prevented from being deformed. Accordingly quality and production of the optical disks are improved.
