ABSTRACT:
A method for producing a recording medium provides good throughput for mass production and reduces cost. The method facilitates the control of the shape or dimensions of a pattern obtained by microfabrication, allows an accurate pattern transfer, and provides superior uniformity. A magnetic layer is formed on a substrate. A nano-particle film16is formed on a desired portion on the magnetic layer. Using the nano-particle film as a mask, the magnetic layer is cut. A micropattern with concavities and convexities is formed on the magnetic layer by removing the nano-particle film.
