Abstract:
According to one embodiment, a magnetic disk device conforming to perpendicular magnetic recording includes a magnetic disk, a recording head, and a controller. The head includes a main magnetic pole, a return magnetic pole, a recording coil, and a conductive member in which end surfaces are connected to opposed surfaces of a write gap which is opposed to a distal portion of the main magnetic pole and a distal portion of the return magnetic pole, and a resistance value varies. The controller applies a current to the recording coil to excite the magnetic flux in the recording operation, and applies a current at a constant voltage to the magnetic circuit via the comductive member.

Claim (Index 6):
A recording head control method of a magnetic disk device comprising a recording head which generates a perpendicular recording magnetic field to a magnetic disk conforming to perpendicular magnetic recording,\n the recording head comprising: a main magnetic pole which generates the perpendicular recording magnetic field; a return magnetic pole which returns a magnetic flux from the main magnetic pole and. forms a magnetic circuit in cooperation with the main magnetic pole; a recording coil which excites the magnetic flux in the magnetic circuit formed of the main magnetic pole and the return magnetic pole; and a conductive member in which end surfaces are connected to opposed surfaces of a write gap which is opposed to a distal portion of the main magnetic pole and a distal portion of the return magnetic pole, and a resistance value varies between a recording operation and a non-recording operation, the recording head control method comprising: applying a current at a constant voltage to the magnetic circuit formed in the main magnetic pole and the return. magnetic pole via the conductive member; and applying a current to the recording coil to excite the magnetic flux in the recording operation, and stopping applying the current in the non-recording operation.
