ABSTRACT:
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.
