Patent ID: 7680018

Claim:
A method for manufacturing an optical recording medium, comprising: a molding step of molding a disc-like shaped substrate including an information recording face at least on one side; a light transmitting layer formation step of forming a light transmitting layer thinner than the substrate on the information recording face; a cutting step of forming a circular cut in the light transmitting layer; and a punching step of punching out at least a part of an area inside the circular cut by a punching tool to divide the light transmitting layer at the circular cut and form both center holes in the light transmitting layer and the substrate, wherein the circular cut in the light transmitting layer is formed at a larger diameter than an inner diameter of the center hole in the substrate, the area inside the circular cut is pressurized in a thickness direction by the punching tool to divide the light transmitting layer at the circular cut and to punch the light transmitting layer and the substrate, thereby forming the center hole at a larger inner diameter than that of the center hole in the substrate in the light transmitting layer, and the molding step, the light transmitting layer formation step, the cutting step and the punching step are conducted in this order.
