Abstract
A method corrects a head suspension by irradiating an objective part of the head suspension with a laser beam before or after mounting a read/write head on the head suspension. The method can precisely correct the head suspension even when correcting the head suspension a plurality of times. The method includes drawing, with the laser beam, a straight line of predetermined length on the objective part and repeating this process a plurality of times in such a way that the direction of a straight line drawn this time crosses the direction of a straight line drawn last time.
