ABSTRACT OF THE DISCLOSURE Tracking control apparatus for a signal reproducing system of the type wherein at least one transducer scans suc- cessive parallel tracks on a record medium in which information signals, such as video signals, are recorded. The transducer preferably is of the rotary type so that, during its orbit, it is brought into and then out of reproducing relation with res- pect to the record medium. Any deviation between the scanning trace of the transducer across the medium and a given track which is being scanned is detected, and a control signal is produced as a function of this detection deviation. The trans- ducer is supported by an adjustable support which is responsive to the control signal so as to displace the transducer trans- versely of the given track by an amount determined by the control signal, A predetermined sample of the control signal is produced while the transducer scans the given track, and this predetermined sample is stored. Prior to the time that the transducer moves into a reproducing relation with respect to the medium, the stored sample is supplied to the adjust- able support so that the transducer is pre-displaced before signals are reproduced thereby.
