REPRODUCING DEVICE OF INFORMATION RECORDING CARRIER

摘要

PURPOSE:To obtain a highly efficient producing device of an information recording carrier with high quality by protruding intentionally liquid resin from the outer peripheries of plural metallic stampers, irradiating radiant rays only to a range to be the information recording carrier to harden the resin and then sucking and discharging the residual liquid resin. CONSTITUTION:Injected resin is pressed up to a prescribed disk thickness. To prevent the resin from mixing with air bubbles more effectively, an extruding mechanism consisting of a compression spring 17 and a center pin 18 is formed on the center part of a substrate and the contact of the liquid resin with the substrate is expanded successively from the center to the outer periphery by said mechanism to improve the air mixing preventing effect. After completing the pressing, the resin film is exposed to light by a radiant ray light source under the pressed status to harden the resin film. After completing the exposure, the liquid resin projected to the outer periphery of the substrate 2 which is unhardened by a mask (radiant ray shielding part) is discharged to the outside of the device by a suction/discharge mechanism through a liquid resin discharging course and a resin discharge pipe 15.
