  • This paper presents numerical simulations on a feedback active control strategy for flow-induced off-track vibration of a head gimbals assembly (HGA) bearing a slider in hard disk drives (HDDs). In the proposed active control strategy, a physical pressure sensor is assumed on the HDD cover to detect the pressure fluctuations and a pressure actuator is on the inner surface of the HDD cover to actuate feedback acoustic pressures to suppress pressure fluctuations in airflow turbulence around the… CONTINUE READING
