Abstract

Vertical magnetic head with an integrated coil and its production process wherein the head comprises two pole pieces (30.sub.2, 30.sub.2) and two integrated coils 50.sub.1, 50.sub.2), which are interconnected by a conductor bridge (75). A magnetic or permeability bridge (70) connects the two pole pieces and closes the circuit.
