Abstract
A method of making a multi-core magnetic head in which two blocks of magnetic, ceramic material, configured to the desired pole piece shape, are joined with the two surfaces defining the gap being glass bonded, and the block cut to form individual pieces which are then glass bonded in grooves in the bottom of a U-shaped non-magnetic holder so that the pieces extend upward into the region bounded by the holder sides. The region is then potted and a carbon fixture placed over the ends of the upwardly extending pieces to provide additional mechanical strength. The potted assembly is then cut to leave upwardly extending pole legs.
