  • 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 measured. The results show a high correspondence between the pressure fluctuations and the HGA off-track vibration. Secondly, a feedback control architecture, based on numerical simulations, is… CONTINUE READING
