Abstract
A recording and/or reproducing apparatus comprises a signal transducer in the form of a single recording and/or reproducing head. A single step-driving device intermittently steps the head from one track position to another track position on a rotating recording medium to read two separate and alternating sets of tracks. Stepping occurs during a vertical blanking period of a video signal. A synthesized synchronizing signal is generated to compensate for any deficiencies of the synchronizing signal, as originally recorded, and as played back within a reproduced video signal.
