  • Patent number: 8786977
    Abstract: Vibration of a transducer slider can be used during slider fly height calibration to detect contact of the transducer slider with a disc surface. Amplification of the vibration may cause the transducer slider to tap the disc surface rather than drag across the disc surface when detecting contact with the disc surface. Amplification may be achieved by applying an in-phase AC signal to the transducer slider at the same frequency as the vibration of the slider. Reduced contact between the slider and the disc surface reduces wear on and the possibility of damage to the transducer slider and/or the disc surface. Once the fly height of the transducer slider is calibrated, the AC signal may be shifted out-of-phase with the slider vibration to dampen the slider vibration.

  • Patent number: 7124497
    Abstract: A method and apparatus are provided characterizing the shape of a surface such as a bearing surface on a slider and for processing the shape. The shape is characterized by fitting a curve having a desired shape to measurement data and then determining residual deviations from the desired shape within localized regions. The surface is processed by selecting a material stress pattern to be applied to a working surface of the slider based on measured and desired contour shape parameters in a plurality of localized areas on the bearing surface. The measured contour shape parameter within a first of the plurality of localized areas is weighted more heavily than those within the other localized areas.
