Abstract

See full text

According to one embodiment, there is provided a magnetic head including a wave guide, a near field transducer, a writing magnetic pole, a magnetic core, a writing coil, and a first temperature control element. The near field transducer is disposed on an ABS surface and to which light is guided from the wave guide. The writing magnetic pole is disposed on the ABS surface. The magnetic core is connected to the writing magnetic pole so as to generate a magnetic field from a portion of the writing magnetic pole close to the ABS surface. The writing coil is disposed so as to go around the magnetic core. The first temperature control element is disposed in contact with a region of a first side surface of the wave guide near the near field transducer.
