ABSTRACT:
To reduce the inductance of a ferrite transducer head, the head is formed of ferrite-type pole pieces laterally extended by non-magnetic material of high wear resistance characteristic to decrease the per-unit application pressure of the tape against the overall head, the pole pieces being connected by a yoke of cross section which is small with respect to that of the pole pieces, the signal transducing coil being wound on the yoke. To provide space for winding of the coil, the pole pieces are formed with recess openings, and the extending non-magnetic support elements are likewise formed with an opening to provide space for the coil. The entire head can be mounted on a support, for example by an adhesive, made of non-magnetic material.
