Abstract
A novel hydrodynamic bearing with non-uniform spiral grooves was proposed for high-speed HDD spindle in this paper. Theoretical approach indicated that the non-uniform grooved bearing expanded the critical bearing number about 123% larger than the classic bearing with uniform grooves. The utility of the proposed bearing for high-speed spindle was experimentally confirmed.
