Effects of compliance of hydrodynamic thrust bearings in hard disk drives on disk vibration

For cantilever-shaft design 2-disk hydrodynamic bearing spindle motors, the compliance of the thrust bearing has little effect on the radial operating vibration amplitudes which are the major contributor to the track misregistration in hard disk drives. At the low frequency range (
