Abstract:
A combined-type thin film magnetic head in which a read head that includes a magnetoresistive device, and an inductive head are laminated, whereinthe inductive head has a magnetic material layer having a space for forming at least a coil layer thereon; the magnetic material layer comprises: a front separate layer opposing a magnetic recording medium; a rear separate layer disposed away from the magnetic recording medium with a gap provided relative to the front separate layer; and an upper core layer having one end thereof coupled to a top portion of the front separate layer and also extending onto the coil layer and the other end thereof connected to a surface opposing the magnetic recording medium via a magnetic gap; the front separate layer serves also as an upper shield layer of a read section and a lower core layer of the inductive head, and supports the coil layer in cooperation with the rear separate layer; a dimension in a track width direction of the front separate layer is larger than a dimension in a direction orthogonal with respect to the track width direction; and the front separate layer is longer than the rear separate layer in the track width direction, and both ends of the front separate layer extend to both sides of the rear separate layer.
