Magnetic head for perpendicular magnetic recording including a heater

摘要

A magnetic head includes a main pole and a heater for heating the main pole. The main pole is shaped to have a receiving space formed therein for receiving at least part of the heater. The at least part of the heater is received in the receiving space. The main pole includes a first layer and a second layer stacked. The receiving space is sandwiched between the first layer and the second layer.

1. A magnetic head for perpendicular magnetic recording, comprising:
a medium facing surface facing a recording medium; a coil producing a magnetic field that corresponds to data to be written on the recording medium, a main pole having an end face located in the medium facing surface, the main pole allowing a magnetic flux that corresponds to the magnetic field produced by the coil to pass, and producing a write magnetic field for writing the data on the recording medium by means of a perpendicular magnetic recording system; and a heater for heating the main pole, wherein the main pole is shaped to have a receiving space formed therein for receiving at least part of the heater, and the at least part of the heater is received in the receiving space.
