<p>A thin film magnetic head (55) includes a shield-type magnetoresistance effect (MR) head section. The shield-type magnetoresistance effect (MR) head section includes: a MR device section within a shield gap, the MR device section exhibiting a giant magnetoresistance effect; and a lead disposed in such a manner that an electric current flows in a direction perpendicular to a film surface of the MR device section. The MR device section includes first and second magnetic films (M2,M1) with a non-magnetic insulating film (T) interposed therebetween. The first magnetic film exhibits soft magnetic properties and is disposed at a first distance from a face of the thin film magnetic head opposing a magnetic recording medium. The second magnetic film (M1) is disposed at a second distance (di) from the face (S) of the thin film magnetic head opposing the magnetic recording medium such that the second distance is greater than the first distance. <IMAGE></p> |
