PROBLEM TO BE SOLVED: To obtain an ultraviolet curable resin material which enables excellent pattern transfer in a method for manufacturing a magnetic recording medium. SOLUTION: The method of manufacturing a magnetic recording medium includes: bonding a surface of a magnetic recording layer and a convex/concave pattern surface of a resin stamper to each other via a coating layer comprising an ultraviolet curable resin material for pattern transfer, containing isobornyl acrylate, an acrylate with a fluorene skeleton, a polyfunctional acrylate, and a polymerization initiator; curing the coating layer of the uncured ultraviolet curable resin material, with ultraviolet ray irradiation; separating the resin stamper; forming a cured ultraviolet curable resin material layer with the convex/concave pattern transferred thereto, on a surface of the magnetic recording layer; dry-etching the surface using the cured ultraviolet curable resin material layer as a mask; and forming the convex/concave pattern on the surface of the magnetic recording layer.
