摘要： A contact magnetic transfer method forms a pattern of magnetized servo regions in the magnetic recording layer of a rigid perpendicular magnetic recording disk. A master disk or template has a rigid or flexible base with a first film of soft magnetic material on the base and a pattern of islands of soft magnetic material on and extending above the first film and recesses between the islands. The slave disk to be servo patterned is either DC magnetized in a first direction perpendicular to the plane of the recording layer or AC-erased. The slave disk is then placed with its outer layer in proximity to the islands of the master template and a magnetic field is applied in a perpendicular direction to magnetize the regions beneath the islands in the same direction as the applied field. In the regions of the recording layer beneath the recesses of the template the magnetization is reversed from that in the regions beneath the islands.

摘要： Recording of preformat information is accomplished by magnetic transfer to a perpendicular magnetic recording medium with a higher density. The method includes: (1) an initialization step, in which a magnetic field is applied to the magnetic recording medium in the direction perpendicular to the medium surface and direction of magnetization of the whole surface of the magnetic recording medium is aligned to one direction perpendicular to the medium surface, and (2) a magnetic transfer step, in which a magnetic field in the longitudinal direction is applied to both a master disk carrying preformat information and the magnetic recording medium with the master disk in close contact with or in proximity to one or both surfaces of the magnetic recording medium.

摘要： A contact magnetic transfer method for forming a pattern of magnetized servo regions in the magnetic recording layer of a rigid magnetic recording disk uses a flexible master disk and a differential gas pressure to press the patterns of the master disk against the slave disk. The master disk is a flexible plastic film with islands of magnetic shielding material extending above the film surface, the islands forming a pattern representative of the servo pattern to be formed in the recording layer of the disk. The plastic film is sealed at the outer periphery of the opening of a pressure chamber with the islands located outside the chamber. The previously DC-magnetized slave disk is brought into gentle contact with the islands and gas pressure inside the chamber is increased to slightly above atmospheric. This controlled pressure presses the islands into contact with the slave disk, at which time a magnet magnetizes the regions of the recording layer not aligned with the islands in the direction opposite to the original DC-magnetized direction. The magnet is located on a rotatable stage within the chamber beneath the plastic film and mounted so that the length of the gap is in the radial direction corresponding to the radius of the slave disk.
