Abstract
Process for producing a magnetic head with a horizontal structure. A planar subassembly is formed having a first pole piece (38), interconnection tracks (40, 42) and intraconnection tracks (32, 34) through the substrate. The connections are surrounded by a guard ring (54, 56, 58). It is then necessary to form a winding, which is connected to tracks (40, 42) and a second pole piece.
