Abstract
A device comprises a recordable disc, a substrate adjacent to the recordable disc, and an actuation mechanism fixed to the substrate. The recordable disc includes a base layer and a recordable layer on the base layer. Additional electrodes or magnetic components may be placed on the base layer to provide electromagnetic or electrostatic forces to rotate the recordable disc when acted on by the actuation mechanism. As an example, the invention may utilize MEMS techniques in order to integrate a disc and motor of a disc drive as a common component.
