摘要： A patterned disk medium includes a disk-shaped flat substrate including a first surface and a second surface located an opposite side of the first surface. First servo pattern areas including portions provided with magnetic members and portions provided with no magnetic members are provided on the first surface. Second servo pattern areas including portions provided with magnetic members and portions provided with no magnetic members are provided on the second surface.

摘要： A magnetic recording apparatus comprises a magnetic field impression unit, a current supplying unit and a controlling unit t. The magnetic field impression unit impresses a magnetic field to a magnetic recording medium. The current supplying unit supplies a current to the magnetic recording medium. The controlling unit makes the current supplying unit supply the current to the magnetic recording medium while making the magnetic field impression unit impress the magnetic field to at least a unit of a magnetic recording unit of the magnetic recording medium. Thus, a information is recorded magnetically by making a direction of a magnetization of the magnetic recording unit of the magnetic recording medium in a predetermined direction.
