Patent ID: 7126785

Claim:
A method of controlling seeking of a transducer that is adjacent to a rotatable data storage disk in a disk drive, the disk drive having a secondary actuator for positioning the transducer over a second range of movement, and a primary actuator for positioning the secondary actuator over a first range of movement that is larger than the second range of movement, the method comprising: controlling the secondary actuator to extend the secondary actuator from a predetermined location within the second range of movement and move the transducer toward a target track on the disk while seeking; controlling the primary actuator to move the secondary actuator toward the target track while simultaneously controlling the secondary actuator to retract the secondary actuator to the predetermined location while maintaining the transducer aligned with the target track; and initiating at least one of reading and writing data on the target track of the disk before the secondary actuator is retracted back to the predetermined location.
