摘要：
A magnetic write head having a write pole with a tapered trailing edge. The write head has a non-magnetic step layer and a non-magnetic bump formed on the front edge of the magnetic step layer. A non-magnetic trailing gap layer is formed over the tapered trailing edge of the write pole and over the non-magnetic bump and over the non-magnetic step layer. A magnetic trailing shield is formed over at least a portion of the non-magnetic gap layer.
