  • Non-destructive detection of slider contamination
    Patent number: 8995080
    Abstract: Apparatus and method for non-destructive detection of contamination on a slider in a data storage device. In some embodiments, the slider supports a read element adjacent a rotating data recording medium. A non-repeatable runout (NRRO) component of a position error signal (PES) obtained from readback signals transduced from the read element is extracted. A power spectral density (PSD) analysis of the NRRO component is performed to identify a peak power level, and slider contamination is detected responsive to the peak power level.
