Abstract
A contact type thin film magnetic head and method of using the same are provided. The contact type thin film magnetic head comprises a head element that is provided on a disk-facing surface of a slider, a magnetic disk, and heating elements disposed in a plane position different from that of the head element. A protective layer covers the heating elements and the head element. The heating elements and the protecting layer are formed on the disk-facing surface of the slider. The protective layer protrudes further toward the magnetic disk than the head element.
Claims2
A method of recording/regenerating using a contact type thin film magnetic head that has a first side in a track width direction and a second side in the track width direction, the first side in the track width direction having a heating element and the second side in the track width direction having no heating element, the method comprising:
- starting rotation of a magnetic disk;
- creating an electrical connection to the heating element wherein the heating element emits heat at the first side in the track width direction to form a protrusion;
- determining whether a predetermined time has passed;
- loading a thin film magnetic head onto the magnetic disk from a retreated position such that the first side in the track width direction comes over the magnetic disk earlier than the second side in the track width direction and the protrusion comes into contact with the magnetic disk;
- determining whether a predetermined time has passed;
- stopping the electrical connection to the heating element;
- and
- operating recording/regenerating using the contact type thin film magnetic head.
