Abstract
A method of joining two manganese zinc ferrite pole pieces, to form a product suitable for use in radio frequency recording apparatus, and especially for multi-core magnetic heads, is disclosed. Chromium layers are formed on each manganese zinc ferrite pole piece, on opposed faces thereof, and then the chromium layers are bonded together by means of a suitable adhesive, such as a high strength epoxy adhesive.
