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.
