Abstract:
A process for producing a vertical magnetic head comprising, the steps of: producing on a substrate an amagnetic spacer having a height (l) above the substrate; depositing on either side of said spacer magnetic material for forming a head gap area, including the steps of, (a) depositing by vapour deposition a layer of a first magnetic material on the substrate and on either side of the spacer in a direction perpendicular to the substrate, wherein the layer of the first magnetic material has a thickness less than or equal to (l), and (b) depositing after the vapour deposition a second magnetic material above the first magnetic material wherein the second magnetic material has inferior mechanical properties to those of the first magnetic material and is thicker than the first magnetic material; and completing a magnetic circuit around the head gap area by associating a conductor winding therewith.
