ABSTRACT:
A method of manufacturing magnetic head cores is provided in which a plurality of separate magnetic head cores is cut from a one-piece ferrite core block. A winding aperture is provided in each magnetic head core. A fracture in the cross-section of the material of the head core is generated by the winding aperture and the future tape contact face during or after the winding aperture is provided. A non-magnetic material in a liquid form is provided between the fracture faces and is converted to the solid form.
