Abstract:
1. A disk drive comprising: a drive circuitry; a suspension; and a slider that is supported by the suspension and receives electrical current from the drive circuitry, the slider including (i) a flying side that is configured to generally face storage media, (ii) a back side that is substantially opposite the flying side, (iii) a read/write head that is capable of magnetically interacting with storage media, the read/write head moving relative to the back side when the temperature of the read/write head changes, and (iv) a slider deformer that is electrically decoupled from the drive circuitry, the slider deformer deforming of a portion of the flying side when the temperature of the slider deformer changes so that the deformation at least partially offsets the movement of the read/write head that occurs when the temperature of the read/write head changes, the slider further includes a support material that contacts the slider deformer, the support material having a first coefficient of thermal expansion, and wherein the slider deformer has a second coefficient of thermal expansion that is at least approximately 25 percent greater than the first coefficient of thermal expansion.
