摘要：
In a method of pre-contact detection and active damping of air bearing vibrations in a hard disk drive, a slider is isolated from ground. The slider is then capacitively coupled with a hard disk of the hard disk drive via a thermal fly-height control (TFC) heating element. An alternating current (AC) signal is applied to the slider via the TFC heating element to control the amplitude of the slider.
