Abstract
One embodiment of the present invention pertains to a slider that includes a substrate, a transducer tip disposed on the substrate, and a hydrodynamic surface including a responsive aeroelastic deposit. The substrate has a first coefficient of expansion responsive to a stimulus. The transducer tip has having a second coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion. The aeroelastic deposit has a third coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion. The responsive aeroelastic deposit allows the slider to alter its flight characteristics responsively and elastically to changing operating conditions.
