摘要： According to one embodiment, there is provided a magnetic recording head which records information on a magnetic recording medium, including an ABS surface, a near-field light generating unit, a heat conducting unit, and a heat absorbing unit. The ABS surface is opposed to the magnetic recording medium. The near-field light generating unit is disposed on the ABS surface. The heat conducting unit is formed by a heat conductor disposed in contact with the near-field light generating unit. The heat absorbing unit is disposed in contact with the heat conducting unit adjacently to the near-field light generating unit in a direction along the ABS surface.

摘要： According to one embodiment, a magnetic head includes a main pole, a write shield pole on a trailing side of the main pole, a recording coil, and a temperature control element unit. The temperature control element unit includes a first electrode on a leading side of the main pole and on both sides of a track of the main pole, a second electrode on the leading side of the main pole and on a track center of the main pole, an N-type semiconductor and a P-type semiconductor connected to the first and second electrodes, and a wiring portion which applies a current via the second electrode, N-type semiconductor, first electrode, P-type semiconductor, and second electrode. The first and second electrodes form a heat absorbing portion and a heat radiating portion.
