Abstract
Methods of filtering a position error signal (PES) indicative of a position of a transducer of a disk drive include obtaining sample position data for the transducer, eliminating selected data of the sample position data to provide a subset of the sample position data, obtaining a plurality of sets of preliminary filter coefficients based on the subset of the sample position data, obtaining a final set of filter coefficients from the plurality of sets of preliminary filter coefficients, and filtering a position error signal using the final set of filter coefficients. Corresponding disk drives are also disclosed.
