Abstract

PURPOSE:To facilitate writing to minute ranges, multiple channelling, etc., by winding a coil for generating a magnetic field so as to include a semiconductor exothermic portion and an amorphous magnetic film. CONSTITUTION:When electricity is added among electrodes 4, 9, joining surfaces generate heat in joining portions 8 by currents in the order direction when the order bias of PN joining and by currents by Zener effect or avalanche effect when inverse bias, amorphous magnetic layers 6 through an insulating layer 5 are heated and magnetic fields are applied from the outside and signals are written when magnetic resisting force lowers. And when breaking currents let flow for joining, an amorphous magnetic body, which magnetic resisting force rises, is contacted with a magnetic record medium and record is transcribed because heat diffuses, joining surface cool and the magnetic resisting force of the magnetic body rises. In this case, the magnetic resisting force of the amorphous magnetic body is made mightier than that of the record medium. Thus, writing to minute ranges, multiple channelling, etc, can be facilitated.
