Abstract
A magnetic flux shield extending substantially the entire width of a magnetic disk drive spindle motor magnet is mounted between the magnet and the disk drive's base frame and rotates with the magnet. The flux shield is formed of a magnetic material to capture any stray magnetic flux from the motor magnet that may produce power draining eddy currents in the base frame.
