Abstract: This thin film magnetic head includes: a magnetic pole including an end surface exposed on an air bearing surface; and a heating element including a first branch and a second branch and configured to heat a vicinity of the magnetic pole. The first branch and the second branch each expand along a stacking surface and are coupled in parallel to each other. The stacking surface intersects the air bearing surface.

Abstract: This thin film magnetic head includes: a magnetic pole including a first end surface exposed on an air bearing surface; a coil configured to provide a magnetic flux passing through inside of the magnetic pole; and a heatsink including a second end surface that is provided at a position recessed from the air bearing surface. The second end surface is configured to suppress reflection causing light that has traveled through an entering position on the air bearing surface to return to the entering position.

Abstract: A magnetic head includes a main pole, a write shield, and a return path section. The write shield includes first and second shield portions located on opposite sides of the main pole in the track width direction. The return path section includes first and second yoke portions located on opposite sides of the main pole in the track width direction. The first yoke portion is connected to the first shield portion. The second yoke portion is connected to the second shield portion. A coil surrounds at least part of the entire outer periphery of the main pole when viewed from a medium facing surface.
