Patent ID: 8670202

Claim:
A magnetic head comprising: a main pole configured to apply a recording magnetic field to a recording layer of a recording medium; a write shield pole on a trailing side of the main pole with a write gap therebetween; a recording coil configured to wind around a magnetic circuit formed of the main pole; and a temperature control element unit comprising: a first electrode on a leading side of the main pole near a floating surface of the magnetic head and on both sides of a track of the main pole in a track width direction; a second electrode on the leading side of the main pole near the floating surface 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 configured to apply a current through the second electrode, the N-type semiconductor, the first electrode, and the P-type semiconductor, wherein the first electrode and the second electrode are configured to form a heat absorbing portion and a heat radiating portion.
