Active control on flow-induced vibration of the head gimbals assembly in hard disk drives
An active control method has been applied for the flow-induced vibration (FIV) of the head gimbals assembly (HGA) in working hard disk drives (HDDs) through suppressing the pressure fluctuations around the HGA. Firstly, the HGA off-track vibrations and the pressure fluctuations around the HGA are me...
