Patent ID: 7898767

Claim:
A perpendicular magnetic recording head comprising: a read part disposed on a substrate to read magnetic recording information from a recording medium by a magnetoresistance effect; a write part disposed above the read part to record magnetic information on the recording medium by applying a perpendicular magnetic field, the write part including a write coil; a heating element disposed between the write coil and the read part, the heating element generating heat when supplied with current so that the read part is thermally expanded to protrude toward the recording medium; a heat-dissipating layer disposed between the write coil and the heating element, the heat-dissipating layer having a heat dissipation effect; and a conductive layer behind the read part and the write part in a height direction, the heat-dissipating layer being connected to the substrate via the conductive layer to transfer heat from the write coil to the substrate, wherein the heat-dissipating layer overlaps with the heating element as seen from a stacking direction of layers constituting the perpendicular magnetic recording head.
