ABSTRACT:
A method and apparatus for detecting slider/disk fly-height modulation in a hard disk drive is provided. A slider is electrically isolating from an electrically grounded suspension. A signal line is coupled to the slider, the signal line for providing an alert signal when a modulation in fly-height between the slider and an electrically grounded disk of the hard disk drive occurs.
