Patent ID: 8203804

Claim:
A head gimbal assembly comprising: a magnetic head for perpendicular recording, comprising a slider and a head section thereon and configured to record data in a recording medium; a suspension supporting the magnetic head; and a heating module configured to locally heat a recording area of the recording medium, the head section comprising: a magnetic core comprising a main pole configured to produce a recording magnetic field, and a return pole opposed to a trailing side of the main pole with a gap to form a magnetic circuit in conjunction with the main pole, a coil configured to excite magnetic flux in the magnetic circuit, and a thermal conductor having thermal conductivity higher than thermal conductivity of the recording medium and comprising a heat absorbing portion configured to oppose the recording medium in the vicinity of the heated region of the recording medium and remove heat from the recording medium, and a contact portion configured to contact airflow produced, as the recording medium rotates, at a position other than a facing surface of the slider opposed to the recording medium and radiate heat.
