The effect of friction force between the head slider and disk on the v
ibration of the head suspension assembly was simulated using,Finite El
ement 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 di
rection of the head suspension was measured using a scanning LDV simul
taneously. The effect of friction force on the vibration with differen
t skew angles was investigated.
