บทคัดย่อ/คำอธิบาย :

The spectrum-spatio characteristics of the pressure fluctuation around the head gimbals assembly (HGA) in an actual HDD is studied experimentally to understand the excitation of the flow-induced vibration (FIV) of the HGA in HDDs. Aerodynamic excitation around the HGA is detected by a proposed method of measuring pressure fluctuation on the cover innersurface of an HDD. The results show that the principal non-repeatable run out (NRRO) peaks in the off-track vibration spectra of the HGA are in narrow bands around 1.83 kHz and 2.54 kHz and are dominated by the aerodynamic pressure fluctuation around the HGA. In addition, aerodynamic pressure disturbance in the narrow space of the HDD is found to remain highly coherent at frequencies around the principle peaks. The proposed method for detecting the aerodynamic pressure disturbance around the HGA is shown to be feasible and can be used for signal sensing in future active control on pressure fluctuation in HDDs.
