Abstract
This magnetic head construction includes two or more elements defining a transducing gap which are positioned and held together within a shell by a wedge. The magnetic head assembly disclosed normally includes a shell structure, a pair of transducer elements defining a transducing gap, a wedge and a wedge follower. The wedge follower may be present as either a separate element or as a surface carried by one of the transducer elements. The assembly is normally formed by the process of disposing the transducer elements, and the wedge follower, if present, within the shell wall, and then rough positioning these elements within the shell, followed by the insertion of the wedge against the wedge following surface to bring the parts into final position in a locked relationship. Generally speaking, locking is achieved by selecting the wedge angle, .theta. as a function of the coefficients of friction of the mating surfaces according to given formulae. This head structure and process requires no additional adhesive, glass, or other material to lock the parts of the structure together.
