摘要
In a feedback control mechanism for active damping of slider air bearing vibrations in a hard disk drive slider, a filter is used to filter a velocity signal from a slider to acquire a vibration signal. A phase-shifter, electrically coupled with the filter, shifts the phase of the vibration signal. An amplifier, electrically coupled with the phase-shifter, adjusts the amplitude of the phase-shifted vibration signal to achieve an amplitude adjusted vibration signal. An electrical coupler couples the amplitude adjusted vibration signal to the slider for actively damping air bearing vibrations in the slider.
