Patent ID: 7839596

Claim:
A method for controlling the effects of seek-induced vibration of a component part in a hard-disk drive, said method comprising: determining a resonant frequency of said seek-induced vibration of said component part and a reference amplitude of a frequency-component in a first position-error signal of a seek of a data track at said resonant frequency and a reference amplitude of a frequency-component in a first voice-coil-motor signal associated with said first position-error signal at said resonant frequency; synthesizing a second voice-coil-motor signal with an amplitude of a frequency-component attenuated below said reference amplitude of said frequency-component in said first voice-coil-motor signal at a frequency in a resonance-band bracketing said resonant frequency; and driving a voice-coil of a voice-coil motor with said second voice-coil-motor signal to reduce an amplitude of a frequency-component at said resonant frequency in a second position-error signal of said seek of said data track associated with said second voice-coil-motor signal below said reference amplitude of said frequency-component in said first position-error signal associated with said first voice-coil-motor signal.
