  • Patent number: 3943624
    Abstract: A method for manufacturing a magnetic head having at least one ferrite pole tip pair. The tips of each pair are separated by non-magnetic gap of a desired length and the method in accordance with the invention utilizes tips having generally planar surfaces. An elongated apex forming channel is formed in one of the pole tips and an elongated reservoir channel is formed in the same tip in generally parallel relationship. The reservoir channel is filled with glass and polished so that the glass therein extends in co-planar relationship to the generally planar surface of the tip having the reservoir channel therein. The generally planar surfaces are placed in opposed spaced relationship and a quantity of glass is disposed in the apex forming channel. All of the glass and both of the tips are heated until the glass from the channels flows into the space intermediate the generally planar faces of the tips.
