Abstract:
A disk drive includes a drive circuitry, a storage disk, a suspension and a slider. The slider is supported by the suspension and receives electrical current from the drive circuitry. The slider includes a flying side that generally faces the storage disk, a read/write head, and a slider deformer that is electrically decoupled from the drive circuitry. In one embodiment, the slider deformer is formed from a material having a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of other portions of the slider. In this embodiment, the slider deformer causes a deformation of a portion of the flying side when the temperature of the slider deformer changes. Thus, when the read/write head expands or contracts due to a change in temperature of the slider, the slider deformer at least partially offsets the expansion and/or contraction of the read/write head to maintain a substantially consistent head-to-disk spacing of the disk drive.
