Abstract
A method and apparatus for adaptive resonance cancellation in a rotating storage system, includes designing a set of digitally selectable optimum resonance cancellation filters, generating a series of excitation signals for injection into the filters, generating a characteristic resonance frequency based on the excitation signals, and computing an address pointer corresponding to the resonance frequency, to select an optimum resonance cancellation filter.
