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.
