摘要： A favorable magnetic transfer is performed to a perpendicular magnetic recording medium. A master medium is provided with a substrate on the surface of which protrusion portions, which form a pattern corresponding to the data that is to be transferred, having a pliable layer thereon have been formed. The master medium is further provided with a soft magnetic layer formed in the depression portions between the protrusion portions, and which is magnetically linked to the soft magnetic layer of the protrusion portions. The soft magnetic layer of the surface of the protrusion portions is conjoined with the magnetic recording layer of a perpendicular magnetic recording medium to form a conjoined body, and a transfer magnetic field is applied to the conjoined body in the direction from the substrate of the master medium toward the slave medium to perform the magnetic transfer.

摘要： A favorable magnetic transfer is performed on a vertical magnetic recording medium. A permanent magnet apparatus employs a transfer magnetic field generating means provided with two columnar permanentmagnets, each having a cross-sectional surface are equal to or greater than that of the track surface of the slave medium. A conjoined body formed of a slave medium, which has been initially magnetized unidirectionally in the direction perpendicular to the track surface thereof, and two master mediums, disposed on respective surfaces of the slave medium, is inserted between the permanent magnets so that a transfer magnetic field can be applied thereto in the direction substantially opposite that in which the initial magnetization has been performed. A uniform transfer magnetic field is applied over the entirety of track surface of the slave medium so as to simultaneously perform a magnetic transfer over the entirety of the track surface.
