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 film 16 is 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.
Claims14
A method for producing a recording medium, comprising the steps of:
- forming a magnetic layer on a substrate;
- forming a nano-particle film on a desired portion of said magnetic layer;
- cutting said magnetic layer using said nano-particle film as a mask;
- and
- forming a pattern in said magnetic layer by removing said nano-particle film, wherein said nano-particle film is formed by forming an adhesive layer on said desired portion of said magnetic layer, and causing nano-particles to be bonded to said adhesive layer,
- wherein said adhesive layer is formed by applying an adhesive to a mold, and transferring said adhesive to said magnetic layer.
