Vibration of head suspensions for proximity recording

The effect of friction force between the head slider and disk on the vibration of the head suspension assembly was simulated using Finite Element Method (FEM) analysis. Vibration of the slider in the transverse direction was measured using a Laser Doppler Vibrometer (LDV) in both the flying and proximity conditions. The vibration in the vertical direction of the head suspension was measured using a scanning LDV simultaneously. The effect of friction force on the vibration with different skew angles was investigated.
