ABSTRACT:
In a method of feedback control for active damping of slider air bearing vibrations in a hard disk drive slider, a slider is isolated from ground. A slider velocity signal is filtered to acquire a vibration signal. The vibration signal is adjusted in amplitude to achieve an amplitude adjusted vibration signal. The amplitude adjusted vibration signal is applied to the slider to actively dampen air bearing vibrations in the slider.
