摘要：
A manufacturing method for a magnetic recording medium stamp manufactures a magnetic recording medium stamp for manufacturing a discrete track-type magnetic recording medium. The manufacturing method includes a step of forming a convex/concave pattern in a resin layer formed on a support substrate, a step of forming a conductive film so as to cover the convex/concave pattern and then forming a metal film on the conductive film by carrying out a plating process, and a step of separating a multilayer structure composed of the conductive film and the metal film from the support substrate.
