Abstract

PURPOSE: To reproduce smooth pictures without causing the great absence of video information by shifting a reproducing element, operating under the tracking control of high-speed search track-shift pulses to the following recording tracks one after another.
CONSTITUTION: Reproducing element 2 brought under the control of tracking servosystem TS is rapidly shifted onto recording tracks one after another by a pulse generated at a random time position by high-speed searching-track-shift-pulse-signal generator 16 whose oscillation frequency varies with a desired search speed to system TS, thereby moving element 2 in the radius direction of video disk 1. Through the movement of the element 2, motor M is driven on the basis of the low- frequency component of a tracking control signal generated in system TS.
