Abstract
The present invention relates to a magnetic head, a manufacturing method therefor, a head assembly, and a magnetic recording/reproducing apparatus. According to the present invention, it includes a magnetic pole layer, a non-magnetic layer, a trailing gap layer, and a trailing shield layer. 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. Moreover, the tapered face extends from a trailing edge of the pole tip at a constant inclination angle.
