摘要： In a method of producing a stamper for roughening a substrate of an optical recording medium, a masking treatment is carried out prior to a blasting treatment, whereby a second pit forming site of a metal plate is protected such that the second pit forming site is not broken in the following blasting treatment. A mask of an adhesive sheet is attached to the second pit forming site in the masking treatment, and then a part of one major surface of the metal plate, exposed between the mask, is roughened in the blasting treatment. An original stamper of the metal plate, having a partly roughened major surface, is obtained by the blasting treatment.
