Abstract
A holographic spinner is mounted to a drive motor via a center drive hub containing a self-aligning bearing. Rotational drive is coupled through to the spinner by one or more drive pins. This arrangement permits centrifugal forces of the spinner to perpendicularly align the spinner to the rotor axis while simultaneously maintaining disc centration and positive drive about the axis.
