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.
Claims38
A slider, comprising:
- a substrate, having a first coefficient of expansion responsive to a stimulus;
- a transducer tip disposed on the substrate, the transducer tip having a second coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion;
- and
- a hydrodynamic surface comprising a responsive aeroelastic deposit having a third coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion.
A slider, comprising a substrate, a transducer disposed on the substrate, and a hydrodynamic surface that comprises:
- a substrate surface having a first coefficient of expansion responsive to a stimulus;
- a transducer tip of the transducer, the transducer tip having a second coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion;
- and
- a means for altering a height of an aeroelastic feature of the hydrodynamic surface relative to both the substrate surface and the transducer tip, responsively to the stimulus.
A data storage system comprising:
- a media surface;
- a head assembly suspended above the media surface;
- and
- a slider suspended from the head assembly at a slider fly height above the media surface, the slider comprising:
- a substrate, having a first coefficient of expansion responsive to a stimulus;
- a transducer tip disposed on the substrate and extending therefrom to a transducer tip height, the transducer tip having a second coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion;
- and
- a hydrodynamic surface, comprising a responsive aeroelastic deposit having a third coefficient of expansion responsive to the stimulus that is greater than the first coefficient of expansion.
