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 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.
