Method of making a magnetic recording/reading head

摘要

A method for the making of a magnetic recording/reading head comprises the following steps: the making of magnetic excitation wires on or in a first face of a substrate having this first face and a second face opposite the first face; the making, on the first or second face of the substrate, of at least two magnetic poles separated by a gap; the drilling of holes through the substrate from the face opposite the one bearing the magnetic poles, each ending in such a way that there is magnetic coupling between the bottom of the hole and the pole; the deposition of a layer of material with high magnetic permeability in the holes and in the zones of the substrate located between the holes. Applications: the making of magnetic recording/reading heads for video-tape recorders, computer peripherals and professional recording machines.
