Abstract: In a method for producing a stamper for an optical information recording medium, a master 6 with a concavo-convex pattern is produced by exposing and developing a master substrate 3 including a resist 2 of an inorganic material formed on a substrate 1. An organic layer 7 is formed by a spin coat method on the concavo-convex pattern of the master 6. A conductive film 8 is formed on the organic layer 7 and a metal layer 9 is formed on the conductive film 8 by a plating. During the plating, the layer 7 prevents the resist from reacting with a conductive film and the metal layer and decomposing electrically. The metal layer 9 alone or together with the conductive film 8 is peeled off from the master 6 and thereby a stamper 10a or 10b having a concavo-convex pattern complementary to that of the master 6 is obtained.

Thereby a coating is obtained which extends on the upper surface of the inner guide member and the first main surface of the flat plate.

Abstract: A method for exposing an optical disk master includes rotating a substrate disk coated with a photoresist, focusing a beam on the photoresist for exposure through an objective lens, and exposing the photoresist so as to form tracks on the substrate disk in its circumferential direction. At this time, the beam is deflected at least temporarily by passing through a deflector. The beam is divided into a first beam and a second beam after passing through the deflector, and the first beam is focused on the photoresist. A difference between the current position and the target position of an optical path of the second beam is detected, and the deflection operation of the deflector is corrected based on the difference so that the optical path of the second beam is located at the target position. This method can improve the track pitch accuracy of an optical disk having a narrow track pitch.
