The fabrication of a multi-track magnetic head assembly is disclosed wherein the assembly is initially formed in two distinct parts, a core housing part carrying a plurality of magnetic core elements and associated winding means, and a face part which carries the transducer pole tips and serves as the head-to-tape transducing surface. The union between the face part of the assembly and the core housing is formed by lapping the surfaces to be joined to a fine finish and assembling the parts such that the respective magnetic components engage one another to complete a magnetic circuit extending from the core element to the associated pole tips and thus through the transducing gaps defined thereby. In order to facilitate re-working of the assembly, the face part is secured to the core housing by only a strip of epoxy adhesive occupying a longitudinal groove in the surface of the core housing adjacent the mated surface of the face part. The face part may be removed for replacement by a simple cutting operation which releases the epoxy bond.
