Abstract
The same recording head or heads may be employed to record both an information signal and a synchronization word signal. Where at least two recording heads provide overlap intervals in the recording of the information signal, the synchronization word signal may be recorded in such overlap intervals. Upon playback, the synchronization word signal may be employed to control at least part of the reproduction of the information signal.
