Abstract

For saving lateral space in a multitrack magnetic head, the connection lead paths (11, 12) run separately side by side along the outside surface of one magnetic layer (13) of the yoke and connect with the conducting strip that runs between the magnetic layers at the open end of the yoke by straps (18, 19) running around the side edges of the upper magnetic layer. Outside the region of the yoke these conductor straps are wider and are superposed one on the other, with an insulating layer between them, for lower resistance loss (see lower part of figure).
