ABSTRACT:
Disclosed herein is a load-sharing type magnetic head, comprising a plurality of mutually independent arrayed magnetic head cores and a plurality of drive lines formed of coils each wound successively on the magnetic head cores in such a manner that the sequence of winding directions of the plurality of coils on each magnetic head core is different from that on all other magnetic head cores in the whole system, whereby the sum of the magnetomotive forces produced by the plurality of coils in the magnetic head cores is amply increased in the selected head core and amply decreased in the remaining cores by properly controlling the direction and/or magnitude of the electric current passed through the drive lines.
