Abstract
A method of manufacturing a novel ferrite magnetic head assembly utilizes two ferrite pieces having extending fingers of closely similar dimensions that are joined in interleaving fashion and bonded to a ceramic substrate. The resultant assembly is sliced to provide closure sections for multi-track magnetic heads. Each closure section is joined to a ferrite wafer such that the wafer and closure section define a transducing gap therebetween.
