Abstract
In one embodiment, the present invention includes an apparatus that includes a circuit that generates control information that controls a height of a read head of a disk drive. The circuit comprises a filter circuit and a detector circuit. The filter circuit receives a read channel signal from the read head and generates a filtered signal. The filtered signal ranges between 1.0 kHz and 500 kHz. The detector circuit receives the filtered signal and generates the control information when the filtered signal exceeds a defined threshold.
