Abstract:
A thin film magnetic head comprising a shield-type magnetoresistance effect (MR) head section including:an MR device section with a shield gap, the MR device section exhibiting a giant magnetoresistance effect; anda first lead and a second lead disposed in such a manner that an electric current flows in a direction which is both perpendicular to a film surface of the MR device section and parallel to a medium surface,wherein the MR device section comprises first and second magnetic films with a non-magnetic insulating film interposed therebetween,the first magnetic film exhibiting soft magnetic properties and being disposed at a first distance from a face of the thin film magnetic head opposing a magnetic recording medium, andthe second magnetic film being disposed at a second distance from the face of the thin film magnetic head opposing the magnetic recording medium such that the second distance is greater than the first distance.
