Abstract:
A thermally-assisted magnetic recording head includes a main pole and a heat sink. The heat sink includes two first portions and two second portions. The two first portions are located on opposite sides of the main pole in the track width direction and are each spaced from the main pole. The two second portions are located between the main pole and the two first portions. The main pole and the two first portions are each formed of a magnetic metal. The two second portions are formed of a nonmagnetic metal.
