Abstract

PURPOSE: To enable junction ferrite magnetic heads of uniform performance to be produced efficiently by alternately laminating single crystal and polycrystal ferrite blanks to an integral unit then cutting the same.
CONSTITUTION: Polycrystal ferrite blanks 11, 13 and single crystal ferrite blank 12 are alternately laminated and the laminate is heated and pressed, whereby the mutual diffused layers 14, 15 are formed. The joined and integrated 3 layers of the blanks are cut at the central part of the blank 12 like an alternate long and short dash line 16. The blank having been cut is further cut along an alternate long and short dash line 17, whereby blanks X, Y are obtained. A notch 18 for mounting winding is formed on the face of the Y opposing to X from the layer 14 across the blank 11 portion. Next, the blanks X, Y are interposed with a magnetic-gap-forming non-magnetic spacer 19 in the opposing faces of the blank 12 portions and are then bonded, after which the assembly is cut along alternate long and short dash lines according to the track width of the magnetic head, whereby the individual magnetic heads are obtained.
