Abstract
A disk drive motor having a capillary bearing seal is provided. In one embodiment, a disk drive motor includes a stationary assembly and a rotating assembly having a fluid dynamic journal bearing disposed therebetween. A capillary seal is defined proximate an upper end of the journal bearing and coupled to at least one re-circulation path. The capillary seal is configured to advantageously retain lubricating fluids within the motor when the motor is subjected to lateral shock.
