Abstract
A disk drive includes a rotatable storage disk, a suspension, and a slider assembly. The slider assembly includes a slider body, a first slider deformer and a second slider deformer. Activation of the first slider deformer deforms the slider body, and activation of the second slider deformer deforms the slider body. Further, the slider deformers can be independently controllable. The read element is positioned near the first slider deformer and the write element is positioned near the second slider deformer. Activation of the first slider deformer adjusts a read head-to-disk spacing of the read element and activation of the second slider deformer adjusts a write head-to-disk spacing of the write element. Further, activation of the first slider deformer does not significantly influence the write head-to-disk spacing and activation of the second slider deformer does not significantly influence the read head-to-disk spacing.
