Abstract:
A method of selecting a dynamic fly height (DFH) control setting for a head in a disk drive is disclosed. The head is servoed over a disk, and a fly height measurement is generated for the head. A frequency component is extracted from the fly height measurement, and the DFH control setting for the head is adjusted in response to the extracted frequency component.
