Abstract

To solve the problem that cost increases due to use of a mold in which a blank stamper is arranged when a laminating face is formed on a dummy disc substrate and time and labor is required when the blank stamper is replaced, and to prevent the laminating face of the dummy disc substrate from being defectively released from the mold and the laminating face from becoming a frosted glass-like surface to give bad influence on the optical disc appearance. A laminating face A1 for the dummy disc substrate A is formed on the mold 11 for molding the disc substrate and a coating comprising at least one of DLC, a nitride compound, a carbide compound and tungsten carbide is applied to a cavity forming face 24a of a mirror plate 24 on which a stamper is not arranged.
