Abstract
Protrusion of head elements to an air bearing surface is effectively reduced and their contact with a recording medium is thereby prevented by forming a level gap (concave) of about 3 nm in a multilayered protective film on the air bearing surface in a part matching an inductive write thin film head in a recording/reproducing separated type magnetic head and thereby offsetting protrusion of the head elements to the air bearing surface due to thermal deformation of the heads.
