A thin film magnetic head includes a lower shielding layer composed of a magnetic material; a nonmagnetic MR gap layer on the lower shielding layer; a magnetoresistive element layer in the MR gap layer facing a recording medium; a lower core layer composed of a magnetic material on the MR gap layer; an upper core layer composed of a magnetic material being opposed to the lower core layer with a nonmagnetic gap layer therebetween at the surface facing the recording medium; and a coil layer for inducing a recording magnetic field in the lower core layer and the upper core layer. Alternatively, a thin film magnetic head further includes a first magnetic material layer in the rear of the lower shielding layer, magnetically separated from the lower shielding layer. A method of fabricating the same is also disclosed.
