Abstract
A data storage device () includes a stator (), a rotor () rotatable about the stator via a pair of bearings (), a cover (), and two data storage disks (). The stator includes a baseplate (), and radially extending stator laminations () under the baseplate. The bearings are fixed in top and bottom ends of the baseplate. The rotor includes a spindle shaft (), a hub (), and a drive member (). The shaft is fixed in the bearings, and the hub is fixed to a top end of the shaft. The drive member is fixed to a bottom end of the shaft, at a side of the baseplate opposite from the hub. The cover is fixed to a bottom of the baseplate, surrounding the drive member. The cover helps prevent contaminants such as dust from entering a clean chamber of the data storage device that surrounds the shaft.
