A method of producing a stamper, an optical recording medium produced by
molding using the stamper, and a method of producing the same, wherein a
base member having a mirror polished main surface and comprising silicon
or glass is formed with a resist film; the resist film is exposed by a
focused electron beam, an ultraviolet ray laser, etc. and developed so as
to form a resist film of a pattern corresponding to relief shapes; the
mirror surface of the base member is processed to relief shapes
(projecting regions and recessed regions) by dry etching etc. using the
obtained resist film as a mask so as to obtain a stamper; the obtained
stamper is used for injection molding to form a medium substrate; and an
optical recording multilayer film and a protective layer are formed to
thereby produce an optical recording medium.
