PURPOSE:To transfer a recorded pattern on a master plate to a magnetic recording medium by interposing the master plate, where magnetic signals are recorded, and the magnetic recording medium, which has an axis of easy magnetization vertical to the surface of a magnetic material film, between magnets such as permanent magnets, electromagnets, or the like and applying a magnetic field. CONSTITUTION:A master plate 20 where magnetic signals are recorded and a magnetic recording medium 21A having an axis of easy magnetization vertical to the surface of a magnetic material film 23A on a base material 22A are interposed between two permanent magnets 27 and 28, and the magnetic field of permanent magnets 27 and 28 is applied to the master plate 20 and the recording medium 21A to transfer magnetic signals, which are recorded on the master plate 20, to the recording medium 21A. Thus, since faithful transfer is possible with a high density and the intensity of the magnetic field for transfer is selected optionally, the vertical magnetic recording medium to which magnetic signals are transferred is not limited to materials having a weak holding force for transfer especially, and easy and faithful transfer is possible whichever magnetic characteristic materials have fundamentally. |
