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.
