摘要： A magnetic transferring apparatus allows attachment of a first magnet to a first holder. A second magnet is attached to a second holder. The first and second holders are located in a space between first and second magnets. A magnetic disk and a master member are located in a space between the first and second holders. The magnetic attraction is generated between the first and second magnets. The magnetic attraction serves to bring the first and second holders closer to each other, so that magnetic pieces of the master member is brought in a close contact with the magnetic disk between the first and second holders. The magnetic flux runs between the first and second based on the contact between the magnetic pieces and the magnetic disk. A servo pattern can in this manner be established in the magnetic disk.

摘要： A master medium is utilized in a magnetic transfer apparatus. The master medium is superposed on a blank magnetic medium. A predetermined magnetic field is then applied to the master medium. The magnetic flux leaks from the master medium between adjacent magnetic pieces on the master medium. The leaked magnetic flux acts on the magnetic medium. The magnetization is accordingly established on the surface of the magnetic medium. Here, spaces can be reduced between the adjacent magnetic pieces on the master medium. Magnetization of a sufficient intensity can reliably be established on the magnetic medium.

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 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.
