PROBLEM TO BE SOLVED: To provide a method for producing a large quantity of stampers for optical disk substrate with high reproducibility by optimizing a land/groove form, and a magneto-optical recording medium using an optical disk produced by this stamper. SOLUTION: In the production method for the stamper for optical disk substrate, by adjusting release layer formation conditions in a process for preparing a 2P mother disk or conductive layer formation conditions in a process for preparing a metal stamper in a process for preparing the 2P mother disk from a 2P master disk and a process for preparing the metal stamper from the 2P mother disk, the form of lands/grooves on the surface of the metal stamper is adjusted. |
