Abstract

PURPOSE: To obtain the titled device, in which an elastic plastic layer transmitting ultraviolet rays is mounted to a lower surface of a cope, the cope is fast stuck to a drag and molding space is made up, and a stamper and the cope are fast stuck completely and which builds up no burr.
CONSTITUTION: An elastic plastic layer 18 transmitting ultraviolet rays is mounted to a lower surface (a surface facing to a drag 1 each other) of a cope 11 formed by a blank transmitting ultraviolet rays. A stamper 31 is installed to the drag 1, and the cope 11 is contracted by proper pressure and fast stuck completely. Burr is not made up to an outer circumference and a central section of a disc injected and molded, and the accuracy of a location of the center does not deteriorate when regenerating the disc and the stability of a picture is not damaged.
