METHODS OF MAKING A CORE FOR A MAGNETIC RECORDING AND REPRODUCING HEAD WITH NARROW TRACK WIDTH

摘要

A method of making a magnetic recording and reproducing component includes, providing in a ferrite member a plurality of grooves defining side-by-side Vee shaped ridges which are reinforced by filling the grooves wwth non-magnetic material. The each ridge apex is then machined to expose a ferrite surface and is bonded to a second ferrite member by means of non-magnetic material so that each face is separated from the second ferrite member by a gap filled with non-magnetic material. A third member is preferably bonded to the second member to produce a second gap aligning with the first gap. Cutting the members between the adjacent ridges to provide a corresponding number of separately operable components.
