Abstract
A component of a disc drive has a coating of a predetermined length on its surface, the coating having at least two separate tapered regions applied in independent steps, the at least two separate tapered regions each having a length that is less than the predetermined length of the component surface. When the component is a shaft of a spindle motor, the ends of the shaft are masked before the tapered regions of coating are applied, and the thickness of the masks covering the shaft ends is varied to control a taper of tapered regions.
