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