Abstract
A spindle system is comprised of a journal and thrust air bearing. The journal bearing has two sets of opposing groove areas. The thrust air bearing has two sets of spiral grooves. The thrust air bearing is gimballed to compensate for misalignment. A bias contact member is connected to the rotating member along the axis of rotation and provides electrical grounding. The spindle system is especially applicable to mounting recording disks in a data storage disk drive.
