Abstract:
1. A method for reworking a head gimbal assembly for disk drive applications, the method comprising: holding a head gimbal assembly comprising a magnetic head slider, the magnetic head slider being physically attached to a portion of the head gimbal assembly; contacting a probe member, coupled to an ultrasonic transducer, to a portion of the magnetic head slider; applying a predetermined power from the ultrasonic transducer to the probe member such that the probe member oscillates at a frequency greater than about 1 k Hz in a linear motion having a spatial displacement of less than 0.03 mm as the probe member is in contact within the portion of the magnetic head slider; causing a repetitive pushing action using the oscillation of the probe member to the magnetic head slider while applying the predetermined power from the ultrasonic transducer to the probe member; separating the magnetic head slider from the head gimbal assembly; and removing the predetermined power from the ultrasonic transducer.
