Magnetic recording/reproducing head manufacturing process and recording/reproducing head

摘要

The method involves forming magnetic excitation wires (2) on or in the first surface (10) of a substrate (1) which includes two opposing surfaces (10,11). On one surface of the substrate a number of magnetic poles (3, 3') are formed, separated by an air gap (30). Holes (12) are pierced through the substrate from the face opposite that carrying the substrate, allowing a magnetic coupling between the base of the hole and the pole. A layer of material having high magnetic permeability (4) is then deposited in the holes and in the region of the substrate between the holes.
