Abstract
A disk drive for storing data includes a drive housing, a storage disk that is rotatably coupled to the drive housing, a slider assembly positioned near the storage disk, and a drive circuitry. The slider assembly includes a head that interacts with the storage disk during a data transfer operation and a slider mover. The drive circuitry directs a first power level to slider mover to maintain the head at a first HtD spacing, and a second power level to the slider mover to maintain the head at a second HtD spacing, and a variable, transition power to the slider mover during a transition between the first power level being directed to the slider mover and the second power level being directed to the slider mover. The transition power is tailored to rapidly move the head between the HtD spacings.
