ABSTRACT:
A perpendicular magnetic recording head includes 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, and including a write coil; a heating element disposed between the write coil and the read part; and a heat-dissipating layer disposed between the write coil and the heating element. The heating element generates heat when supplied with current so that the read part is thermally expanded to protrude toward the recording medium. The heat-dissipating layer has a heat dissipation effect.
