ABSTRACT:
A videodisc reader head positioning control system stores the keyed-in address for a desired picture frame and compares it to the track address for the frames during passage of the reader head toward the desired frame. Logic circuitry distinguishes the difference between the desired address and the address of the head's current position in order to control the head positioning unit at a fast, intermediate, or precision speed. Upon reaching the desired address, the logic circuitry maintains the position of the head for stop frame display of the picture information.
