ABSTRACT:
A magnetic transducer has a transducing gap that is wider than that used for transferring information signals with respect to a magnetic record medium. A magnetic control flux is applied to the transducer to enable a selected segment of the transducing gap, which defines a transducing zone, for transferring information signals with respect to a selected path along the magnetic record medium. Registration of the transducing zone over the selected path is maintained by varying the applied magnetic control flux to thereby move the transducing zone along the wider transducing gap so as to compensate for deviations between the path traced by the transducing zone over the magnetic record medium and the selected path.
