Beschreibung
Zusammenfassung:	An apparatus for manufacturing an optical disc master, having (a) a turntable upon which is received a disc having a resist layer composed of a resist material, the resist material comprising an incomplete oxide of a transition metal 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, which increases the absorption of ultraviolet rays and visible light rays, the resist material being an amorphous inorganic material containing an oxide; and (b) an exposure system operatively configured to selectively expose the resist layer to ultraviolet rays or visible light.
