1352509 Making magnetic heads INTERNATIONAL COMPUTERS Ltd 1 July 1971 [23 Sept 1970] 45197/70 Heading G5R Three or more ferrite members 10, 11 are stacked so that at each interface a planar surface 30, 31 confronts a profiled surface and each intermediate member of the stack has one planar and one profiled surface, a bond of non- magnetic material is formed at each interface, and the stack is cut along planes 17 parallel to the interfaces to provide head cores each consisting of at least part of two adjacent ferrite members, Fig. 3 (not shown). As shown, the stack is cut also along planes 16, 18 and 28 and along a plurality of planes parallel to planes 18 and 28. Each profiled surface includes two flat areas, spaced apart in a plane, to which the neighbouring planar surface 30, 31 is bonded, e.g. by glass 26, 27. |
