Patent ID: 8045286

Claim:
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.
