Patent ID: 7224546

Claim:
A disk drive comprising: (a) a disk comprising a plurality of tracks; (b) a head attached to a distal end of an actuator arm; (c) a voice coil motor (VCM) for rotating the actuator arm about a pivot to actuate the head over the disk; and (d) disk drive control circuitry for: measuring a latching characteristic associated with latching the actuator arm; configuring a latching parameter in response to the measured latching characteristic, the latching parameter for reducing acoustic noise when latching the actuator arm; and using the latching parameter to latch the actuator arm by: seeking the head to a latching track; maintaining the head over the latching track for a predetermined interval; applying an acceleration pulse to the VCM for an acceleration pulse period; applying a braking pulse to the VCM for a brake pulse period; and applying a latching current to the VCM.
