A disk drive includes a slider assembly and a controller that directs
current to the slider assembly to dynamically adjust the head-to-disk
spacing. In one embodiment, the slider assembly includes a write element
having a first end, a second end and an intermediate section, a conductor
that is connected to the intermediate section. In this embodiment, the
controller directs electrical current through the conductor to heat the
write element without writing data to a storage disk. The electrical
current can be directed through the conductor at any time prior to data
transfer or during data transfer. Heating the write element causes a
deformation of the slider assembly to decrease the head-to-disk spacing.
In another embodiment, the slider assembly includes a separate slider
deformer. Electrical current is selectively directed to the slider
deformer to cause a deformation of the slider assembly to obtain a
desired head-to-disk spacing. The slider deformer can include
electrically conductive material or can be a piezoelectric element.
Further, the slider deformer can be serpentine-shaped or substantially
planar in shape.
