Abstract
This thin film magnetic head includes a magnetic pole including an end surface exposed on an air bearing surface, and a contact detection section including a magnetic material layer provided near the air bearing surface, and a magnetic-domain stabilizing structure stabilizing a magnetic domain structure of the magnetic material layer.
Claims13
A thin film magnetic head comprising:
- a magnetic pole including an end surface exposed on an air bearing surface facing a medium;
- and
- a contact detection section including a magnetic material layer provided near the air bearing surface, and a magnetic-domain stabilizer that is configured to stabilize a magnetic domain structure of the magnetic material layer,
- wherein the contact detection section is configured to detect contact between the medium and the air bearing surface.
