Abstract

PURPOSE: To lessen an influence of an adjacent magnetic head element by connecting magnetic head elements via a shield spacer of a needed track interval between front core parts and that of greater thickness between back core parts.
CONSTITUTION: A front core of length l with magnetic gaps 4 of required gap width between side cores 1a and 1b and shield plate 10 bonded to a back core of length m with a center plate with inserted winding 12 are coupled with each other magnetically to form a magnetic head element. This element should have the surface of shield plate 10 agreeing with the flank of the front core in the same plane. Two magnetic head elements A and B are connected together with magnetic shield spacer 13 interposed so as to constituting an erase head for two tracks. Since this head has the thick shield of its winding part, an influence of an adjacent element is lessened. A fixed recording track can therefore be erased without exerting a bad influence on any other track than a recording track to be erased.
