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.
Claims5
A load-sharing type magnetic head, comprising:
- a plurality of mutually independent head cores;
- and
- a plurality of serial drive lines each wound successively on the respective head cores to form coils on each head core, with the sequence of said coils on each head core differing in winding direction from that on any other head core in the whole system, whereby electric currents each having a polarity so determined that said coils on one selected head core produce magnetic fluxes in the same direction are respectively supplied to all of said coils thereby causing one selected head core to be excited to an amply large extent to consequently permit signals to be recorded in a selected one of tracks on a recording medium.
A load-sharing type magnetic head, comprising:
- a plurality of mutually independent head cores;
- and
- a plurality of serial drive lines each wound successively on the respective head cores to form coils on each head core, with the sequence of said coils on each head core differing in winding direction from that on any other head core in the whole system, whereby magnetic signals from the recording medium are delivered to a plurality of head cores in order to generate a magnetomotive force in the coils wound on the head cores in such a manner as to cause the plurality of drive lines to issue potential signals in order to read out the magnetic signals from the recording medium in conformity with a pattern of the potential differences from the drive lines whereby each of said magnetic signals from said recording medium produces a corresponding potential signal differing from every other magnetic signal read out from said recording medium.
