Abstract:
This thin film magnetic head has a magnetic read head and a magnetic write head each having respective end surfaces exposed to an ABS. The magnetic read head includes a magnetic reader including an end surface exposed to the ABS, first heat generator disposed on an opposite side of the magnetic reader from the ABS, and first temperature detector disposed closer to the ABS than the first heat generator is. The magnetic write head includes a magnetic pole having an end surface exposed to the ABS, second heat generator, and second temperature detector disposed closer to the ABS than the second heat generator is. The first heat generator and the first temperature detector adjust the protrusion of the magnetic read head, and the second heat generator and the second temperature detector adjust the protrusion of the magnetic write head.
