A perpendicular write head, the write head having an air bearing surface, the write head including a magnetic write pole, wherein at the air bearing surface, the write pole has a trailing side, a leading side that is opposite the trailing side, and first and second sides; side gaps, wherein the side gaps are proximate the write pole along the first and second side edges; and side shields proximate the side gaps, wherein the side shields have gap facing surfaces and include at least one set of alternating layers of magnetic and non-magnetic materials, wherein only one kind of material makes up the gap facing surfaces at the air bearing surfaces.

Perpendicular write head with laminated side shields

An apparatus that includes a write element including a write element tip having a leading edge, a trailing edge, and first and second side edges connecting the leading edge to the trailing edge, wherein the trailing edge is non-planar; a trailing shield proximate the trailing edge of the write element; a first side shield proximate the first side edge; and a second edge proximate the second side edge.
