Abstract:
1. A magnetic head comprising a magnetic pole layer, a non-magnetic layer, a trailing gap layer, and a trailing shield layer, wherein the magnetic pole layer has a pole tip exposed on a magnetic medium-facing surface, the non-magnetic layer is laid on the magnetic pole layer, the trailing shield layer is exposed on the magnetic medium-facing surface and laid over the magnetic pole layer and the non-magnetic layer with the trailing gap layer between, the magnetic pole layer and the non-magnetic layer have a continuous tapered face opposed to a lower side of the trailing shield layer, and the tapered face extends from a trailing edge of the pole tip at a constant inclination angle, and the non-magnetic layer has an end face extending from a rear end of the tapered face as seen from the magnetic medium-facing surface, and the end face is opposed to a rear end of the trailing shield layer across the trailing gap layer.
