The title device was composed of a modifying cct. (15) for low freq. error a turntable breaking device (17) connected with (15), modifying cct. (18) for high freq. error compensating the excess error of the effective region of (15), cartridge arm (20) connected with (18) and synchronous separator (21) dividing the inform. of the time modulation. To remove the transition phenomenon, device (16) is operated before device (15) maintaining const. disk velocity.
