Abstract: The video disc player has a carriage executing a translational movement in a manner according to the radial movement of the track-following stylus during replay. One end of the stylus arm is flexibly linked to the carriage in such a way that the stylus projects through a hole in the carriage when the arm is lowered for replay. The stylus arm has a magnetic element in the region of its stylus carrying end. An electromagnet produces a controllable magnetic field of given polarity when excited and is fixed to the carriage near the magnetic element. The electromagnet is excited selectively in order to displace the stylus radially.
