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.
Claims4
A multitrack magnetic head assembly comprising:
- a nonmagnetic substrate;
- at least three equal width, uniformly spaced magnetic blocks arranged in a row and joined at their respective first faces to one surface of said substrate for forming a closure section;
- a magnetic wafer disposed a preselected distance from, and joined to, another surface of said substrate substantially perpendicular to said one surface and to respective second faces of said magnetic blocks that are substantially perpendicular to said first faces, said preselected distance defining a common transducing gap for respective magnetic head elements defined between each magnetic block and the common magnetic wafer, thereby to provide a composite head assembly capable of concurrently processing data from multiple tracks of a multiple track magnetic recording medium.
