ABSTRACT:
Disclosed is a disk drive having an enclosure for housing one or more disks, an actuator arm and sliders attached to the actuator arm. The sliders include magnetic transducers for reading information related to data off the disk and for writing representations of data to the disk. In a disk drive with an in-hub, fixed spindle shaft motor, the disk or disks are attached to the hub which is rotatably mounted to the spindle shaft. The hub includes one or more fingers attached to the hub which touch the spindle shaft when the hub is stationary and when the hub is rotating. The spindle shaft may also be provided with a wear resistant layer and/or ring of conductive material to enhance the electrical pathway between the hub and the spindle shaft and provide for lower wear and a longer life.
