ABSTRACT:
A spindle motor assembly which utilizes a ionized air bearing to provide a conductive path through the assembly. The spindle motor assembly includes a spindle shaft that is located within a housing and rotated by an internal motor. The assembly also contains an air bearing which allows relative movement between the spindle shaft and the housing. The air bearing is supplied by a source of air that is ionized by an ionizer. The ionized air provides a conductive path between the spindle and the housing. The spindle may be coupled to a clamp that holds a magnetic disk within a disk certifier. The magnetic disk is electrically grounded to the housing through the chuck, the spindle and the ionized air bearing.
