A disk drive includes a drive housing, a storage disk, a slider and a
drive circuitry. The storage disk has an inner and an outer diameter. The
slider includes a read/write head and a slider mover that receives power
from the drive circuitry to position the read/write head at a
predetermined head-to-disk spacing during radial movement of the slider
relative to the storage disk. The drive circuitry can direct a varying
level of power to the slider mover during radial movement of the slider.
In addition, the drive circuitry can increase the power to the slider
mover as the read/write head nears a target track in order to decrease
the head-to-disk spacing at the appropriate time. The drive circuitry can
adjust the power to the slider mover so that the head-to-disk spacing
remains within a predetermined range as the slider moves radially
relative to the storage disk. The drive circuitry can also direct power
to the slider mover so that the head-to-disk spacing is substantially the
same at the start of a seek operation and when the read/write head
arrives at a target track. The drive circuitry can also direct power to
the slider mover based at least partially on the temperature of a portion
of the slider.
