ABSTRACT:
Device for reading-out a disk-shaped record carrier. To compensate for time-base errors of the detected signal caused by eccentricity or out-of-roundness of the record carrier, a tangential tracking system is provided with which the tangential position of the scanning point on the record carrier can be controlled. A control signal for this tangential tracking system is obtained by extracting the line synchronizing signal from the detected video signal. By ensuring through the use of a filter element that the overall transfer function of the control system exhibits a band-pass characteristic about the frequency which corresponds to the speed of the record carrier, a suitable tangential tracking is ensured.
