摘要： A magnetic pattern transfer method is disclosed. A magnetic pattern transfer master having a plurality of magnetic portions preformed with predetermined magnetic patterns is brought in proximity to a magnetic recording medium having a magnetic film to record the magnetic information, and a magnetic field is applied from an external source thereby to transfer the magnetic patterns to the magnetic recording medium. In order to improve the closeness between the magnetic film of the magnetic recording medium and the magnetic portions of the magnetic pattern transfer master, the magnetic patterns are transferred to the magnetic film of the magnetic recording medium during the process of fabricating the magnetic recording medium. Also, using a magnetic pattern transfer master with the width of each pattern groove of the magnetic patterns smaller than the width of a corresponding pattern protrusion, the relative position of the magnetic pattern transfer master is displaced, while at the same time transferring the magnetic patterns to the magnetic film of the magnetic recording medium a plurality of times.

摘要： The present invention provides a master disk that can easily be brought into contact with and separated from a magnetic recording medium, and can accommodate foreign matters. This master disk transfers a predetermined magnetic pattern onto a magnetic recording medium that can record magnetic information. In the master disk, there are a magnetic pattern formation region in which the magnetic pattern is formed, and a blank region in which the magnetic pattern is not formed. A concave portion for accommodating foreign matters is formed in at least one part of the blank region.

摘要： A magnetic-pattern transferring method is a method for transferring a magnetic pattern to a magnetic recording medium. The method comprises steps as follows. In a master transferring step, a magnetic field is applied to a master placed close to the magnetic recording medium. The magnetic field excites a magnetic layer having a pattern patterned on the master according to the magnetic pattern. Thereby, the pattern of the magnetic layer is transferred to the magnetic recording medium. In a pattern-difference measuring step, a magnetic condition of the magnetic recording medium is measured so as to measure a magnetically different part between the pattern transferred to the magnetic recording medium and the magnetic pattern. In a magnetic transferring step, a pattern transfer is performed to the magnetic recording medium by using the master while applying the magnetic field so as to correct a magnetic condition of the magnetically different part.

摘要： A magnetic transfer apparatus is utilized to establish magnetization on the surface of a magnetic disk. A support mechanism supports the magnetic disk in the magnetic transfer apparatus. A magnetizing mechanism is designed to get opposed to the magnetic disk held by the support mechanism. The magnetizing mechanism applies a magnetic field of variable intensity in response to a change of position in the radial direction of the magnetic disk. The magnetic transfer apparatus enables establishment of a magnetic field of an appropriate intensity at any positions in the radial direction of the magnetic disk. Magnetization of a constant intensity can be established over the surface of the magnetic disk irrespective of a position in the radial direction of the magnetic disk. The magnetic transfer apparatus alone serves to establish a servo pattern of a clear magnetization on the magnetic disk.

摘要： A writer for head positioning information, or a so-called servo track writer allows the read gap to follow a track which has been established on a recording medium or disk. As long as the read gap keeps following the existing track, the write gap is allowed to move along a path extending in parallel with the existing track. The write gap is utilized to write head positioning or servo information into the recording medium along the path. Even when the recording medium suffers from vibration or the like, the read gap can follow the track. The head positioning information can thus be written into the recording medium so as to establish a head positioning pattern at a higher positional accuracy.
