Abstract
The present invention provides a method of manufacturing a master recording medium used for magnetic transfer and having a concavo-convex pattern formed on a surface of the recording medium, the method comprising: a surface treatment step of forming the concavo-convex pattern on a surface of a metal plate to fabricate a metal master disk; a monomolecular layer forming step of forming a monomolecular layer on a surface of the metal master disk, the surface having the concavo-convex pattern formed thereon; a metallic substrate forming step of dipping the metal master disk having the monomolecular layer formed thereon into a plating solution and forming the master recording medium by plating on the surface of the metal master disk, the surface having the monomolecular layer formed thereon; and an exfoliating step of exfoliating the master recording medium from the metal master disk.
