Magnetic transducer structure with improved mechanical coupling and method of manufacturing

摘要

A magnetic transducer assembly having separate core portions with keyways provided therein. The core portions are assembled to form a substantially closed magnetic circuit defining a transducing gap. The keyways form recesses which are contiguous with a transducer inner space provided by the assembled cores. The inner space and recesses are filled with a non-magnetic bonding material. The resulting bond improves the mechanical coupling between the core portions.
