Abstract

PURPOSE:To prevent the damage of core and to make easy the manufacture, by fitting the plate shape auxiliary core at the both sides of the plate shape core, and fitting the cores forming convex groove at one side of the fitted body by opposing each other. CONSTITUTION:At the both sides of the core 9 made of metal magnetic material having the thickness of the track width of required recording or more, the auxiliary cores 10, 10' different in magnetic characters are fitted to form the convex groove 14 being the wiring groove at the side of the cores. After mirror polishing the surface on which the groove 14 is formed, the both cores are jointed by opposing the surfaces and inserting a given non-magnetic material to form the head cap 19 of a given width.
