摘要:
Disclosed herein is a process for producing a structured material, comprising the steps of forming a film on a substrate, forming a plurality of holes in a first region of the film, forming a plurality of holes composed of a hole wall member different from a hole wall member of the holes contained in the first region in a second region other than the first region, filling the holes in the first and second regions with the same material, and modifying the material in at least one region of the first and second regions by a heat treatment.

A method of producing a mold having an uneven structure and a mold for an optical element are provided. The method includes forming on a nickel substrate a mixed film using nickel and a material which phase separates from nickel simultaneously, the mixed film including a plurality of cylinders including nickel as a component thereof and a matrix region including the material which phase separates from nickel as a component thereof and surrounding the plurality of cylinders; and removing the matrix portion from the mixed film by etching to give a mold including nickel or a nickel alloy. The uneven structure is disposed in plurality on the substrate, and a pitch of the uneven structure is within a range of 30 nm or more and 500 nm or less and a depth of the uneven structure is within a range of 100 nm or more.

A magnetic recording medium is provided which is contaminated less and improved in magnetic properties. The process for producing a magnetic recording medium having a recording layer constituted of magnetic granule portions dispersed in a nonmagnetic matrix portion comprises a first step of forming, on a base body, a nonmagnetic matrix portion, and Cu or Ag granule portions dispersed therein by a gas-phase deposition method, a second step of laminating magnetic granule portions on the Cu or Ag granule portions and laminating an additional nonmagnetic matrix portion on the nonmagnetic matrix portion formed in the first step, and a third step of heat-treating the laminate.
