ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for use in a record/playback system for providing improved alignment between a transducer and a recording medium on which information on has been recorded. The direction and magnitude of any misalign- ment between the transducer and the recording medium is rep- resented by an error signal. When the error signal indicates substantial alignment between the transducer and the record- ing medium a train of equally spaced pulses is generated. When the error signal indicates misalignment between the transducer and the recording medium, at least one pulse is either added or deleted from the train of pulses depending on the direction of misalignment indicated by the error signal. The pulse train is then used to generate a drive signal for effecting relative motion between the transducer and the recording medium, the phase of the drive signal varying in response to the addition of deletion of pulses from the pulse train. The drive signal has a constant phase when the pulses are equally spaced, and has its phase altered in one of two selected directions when pulses are either added or deleted from the pulse train. By thus varying the phase of the drive signal, alignment between the transducer and the recording medium is improved. -1-
