Abstract
A load applied to a slider by a suspension is adjusted as follows. First, the suspension is held while no external force to bend the suspension is applied to the suspension. Then, in this state, a position of a load beam is measured with a position measuring instrument. From the information on the position, a pitch angle of the load beam is determined, and conditions for laser light irradiation are determined from the pitch angle. Under the conditions thus determined, laser light is projected onto the front face or the rear face of a bent section of the load beam of the suspension.
Claims18
A method for adjusting a load applied to a flying-type head slider by a suspension that supports the slider, the load being applied under conditions equivalent to those where the slider is flying, the method including the steps of:
- holding the suspension while no external force to bend the suspension is applied to the suspension;
- and
- applying heat energy to the suspension to increase or decrease the load.
An apparatus for adjusting a load applied to a flying-type head slider by a suspension that supports the slider, the load being applied under conditions equivalent to those where the slider is flying, the apparatus comprising:
- holding means for holding the suspension while no external force to bend the suspension is applied to the suspension;
- and
- heat energy applying means for applying heat energy to the suspension to increase or decrease the load.
An apparatus for adjusting a load applied to a flying-type head slider by a suspension that supports the slider, the load being applied under conditions equivalent to those where the slider is flying, the apparatus comprising:
- a holder for holding the suspension while no external force to bend the suspension is applied to the suspension;
- and
- a heat energy applying device for applying heat energy to the suspension to increase or decrease the load.
