摘要： A signal such as a servo tracking signal is recorded on a flexible slave medium by magnetic transfer. When forming the flexible slave medium of a magnetic strip in a continuous length, the signal is recorded on the magnetic strip by patterned master magnetic transfer prior to or simultaneously with shaping the magnetic strip into a desired shape.

摘要： Magnetic field absorbing regions, composed of protrusions or magnetic layers, are provided in an amplitude servo transfer pattern of a patterned master carrier for magnetic transfer. The magnetic field absorbing regions are provided in intermediate tracks between burst bit elements that constitute burst bit strings, which are provided adjacent to each other in a track width direction. The amplitude servo transfer pattern in magnetically transferred onto a magnetic recording medium. Portions of the magnetic recording medium corresponding to the magnetic field absorbing regions become magnetically non-inverted regions. Therefore, noise is not recorded, and servo tracking can be favorably performed.
