Abstract:
A magnetic head includes a main pole, an expansion member, and a heater. The main pole has an end face located in a medium facing surface. The expansion member is located farther from the medium facing surface than is the main pole and adjacent to the main pole in a direction perpendicular to the medium facing surface. The heater heats the expansion member. The expansion member has a linear expansion coefficient higher than that of the main pole.
