Abstract

The control system manages the storage and retrieval of data with respect to a rotating media, wherein an actuator is utilized in the selection of data for storage and retrieval. The control system includes a low level media control circuit that permits the selection of the rotational position of the rotating media and an actuator control circuit that permits the selection of the position of the actuator with respect to the rotating media. A system controller is utilized to direct the operation of the low level media and actuator control circuits whereby the system controller specifies and adjusts, in real time, the incremental selection of the rotational position of the rotating media and the position of the actuator with respect to the rotating media. In the preferred embodiment of the present invention, the system controller is a programmable microcontroller operating in closed loop, event driven response to the occurrence of control information and data stored by the rotating media so that all essential operation required for the successful storage and retrieval of data with respect to the rotating media are performed concurrently and in real time by the microcontroller.
