A pole tip shield for a write element of a recording head is disclosed. The pole tip shield is spaced from the pole tip in the leading edge direction to provide a magnetic wall angle to reduce ATI or adjacent track erasure to compensate for the skew angle of the head. In illustrated embodiments, the pole tip shield includes side portions. In illustrated embodiments the pole tip shield is generally “U” shaped and side portions of the pole tip shield include different thickness or width dimensions. In illustrated embodiments, the pole tip shield provides a magnetic wall angle for a rectangular shaped pole tip. Embodiments disclosed in the application include a trailing edge shield separated from the pole tip shield along an air bearing surface of the head by a non-magnetic gap portion.
