ABSTRACT:
An apparatus for automatically adjusting the playback position of the magnetic data recording device of the kind in which a rotating magnetic head is contacted with a stationary recording tape for recording the data on the tape and the tape is then advanced a predetermined length for recording the next data on the recording tape. The apparatus is designed to prevent the non-registration between the playback head position and the recorded zones of the tape and, to this end, a differential gearing is provided between the capstan shaft adapted for reeling out or unwinding of the tape and the driving shaft for said capstan shaft and operated to compensate for any non-registration between the playback head position and the recorded zones of the tape and automatically bringing the playback head at the edge of the recorded zone in the tape in good timing with the feed of the tape.
