Threaded Rod Work Carrier Patents (Class 72/405.04)
  • Patent number: 8196443
    Abstract: A method corrects a head suspension by irradiating an objective part of the head suspension with a laser beam. The method is capable of precisely correcting the head suspension even when correcting the head suspension a plurality of times. The method removes residual stress created by the preceding correction from the head suspension, and then, carries out the next correction. Accordingly, the method can precisely correct the objective part of the head suspension with a laser beam even if the objective part has once been irradiated with a laser beam in the preceding correction.
