ABSTRACT:
Members of magnetic material are attached at a front end surface of a multichannel magnetic transducer to form an asymmetric magnetic circuit. A member is attached to one magnetic pole of each pair of poles forming a transducing channel. The members on consecutive adjacent channels are attached alternatively to poles located on the opposite sides of the transducer front end surface. The members are placed out of contact with the recording medium and at a distance from the transducing gaps to prevent magnetic coupling therewith, respectively.
