Abstract
A vertical recording head includes a W-shaped core, a substrate carrying a thin film probe supported in one slot of the core, and a shield coil wound in the slots to hold the substrate and assemblage together. A non-magnetic cap forms the surface of the head over the cap, with the arrangement being such that the probe extends through the cap so the magnetic gap is as small as possible.
