摘要：<P>PROBLEM TO BE SOLVED: To provide a magnetic transfer method capable of enhancing quality of a transfer signal formed on a magnetic recording medium and to provide the magnetic recording medium to which magnetic information is transferred by the magnetic transfer method. Ž<P>SOLUTION: The magnetic transfer method includes: an initial magnetizing process for initially magnetizing a perpendicular magnetic recording medium in a perpendicular direction; a closely attaching process for closely attaching a magnetic transfer master carrier to the initially magnetized perpendicular magnetic recording medium; a magnetic transfer process for transferring magnetic information to the perpendicular magnetic recording medium by applying a perpendicular magnetic field which acts in the opposite direction to the direction of the initial magnetization, to the perpendicular magnetic recording medium and the magnetic transfer master carrier closely attached to each other; and a separating process for separating the magnetic transfer master carrier, which is closely attached to the perpendicular magnetic recording medium, from the perpendicular magnetic recording medium. In the magnetic transfer method, the magnetic transfer master carrier is separated from the perpendicular magnetic recording medium while applying another perpendicular magnetic field which acts in the opposite direction to the direction of the initial magnetization in the separating process.
