摘要 |
A method for manufacturing an optical disc master using an existing exposure system, and a method for manufacturing an optical disc having higher recording capacity. The method for manufacturing an optical disc, using a master to produce the optical disc having an irregular pattern thereon, the master being produced by the steps of forming a resist layer composed of a resist material including an incomplete oxide of a transition metal such as W or Mo on a substrate, the oxygen content of the incomplete oxide being smaller than the oxygen content of the stoichiometric composition corresponding to a valence of the transition metal; selectively exposing the resist layer with laser according to a recording signal pattern; and developing the resist layer to form the predetermined irregular pattern. <IMAGE> |
