Abstract
A magnetic head slider with at least one thin-film magnetic head element on a suspension is mounted. This mounting includes electrically connecting the magnetic head slider with the suspension with ball bonding connections. Electrical property of the thin-film magnetic head element is inspected, and then the ball bonding connections are separated when it is judged that the thin-film magnetic head element has defective electrical property. Then, the magnetic head slider is detached from the suspension, and thereafter a new magnetic head slider with at least one thin-film magnetic head element is mounted on the suspension from which the magnetic head slider was detached.
