A method of operating a signal recording and reproducing apparatus is disclosed whereby generally continuously and noise-free transfers of signal information are obtained while reproducing the information from a magnetic tape being transported at a changing speed. The apparatus is of the type which utilizes transverse positioning of the transducing head to accurately follow a track during reproducing. While the tape is transported at speeds other than the normal record and reproduce speed, transport derived signals are employed to control the tape transport servo. When the normal speed is attained, the reproduced signal is detected to determine whether synchronous reproduction conditions have been achieved. If synchronous reproduction conditions are not achieved, the transducing head is moved to a new track to effect synchronous reproduction of the signal information. After synchronous reproduction of the signal information has been achieved, tape control track derived signals are employed to control the tape transport servo.
