ABSTRACT:
Apparatus for reproducing information carried along a spiral track of a record disc having a controller to locate a reproduction element so that it follows the information track and to maintain a substantially linear reproduction speed as the reproduction element recovers the information recorded along the information track at a normal rhythm. The controller compares the progression of the recovery of the information with a time-based reference signal and delivers a control signal when a predetermined difference occurs indicative of a break in the rhythm of the progression of the recovery. The control signal corrects the relative movement between the record disc and the reproduction element to restore the rhythm of the progression of the recovery.
