Patent ID: 8634162

Claim:
A magnetic write head formed on a slider for magnetic data recording, comprising: a magnetic write head formed on the slider, the write head comprising: a magnetic write pole core portion having an end terminating at an air bearing surface and having a trailing edge surface and first and second sides; a magnetic write pole shell portion contacting and surrounding a portion of the trailing edge surface and first and second sides of the magnetic write pole core portion and terminating at an end surface disposed at a first distance from the air bearing surface; a non-magnetic spacer layer surrounding a portion of the magnetic write pole shell portion, the non-magnetic spacer layer having an end surface disposed at a second distance from the air bearing surface, the second distance being greater than the first distance; and a magnetic trailing shield disposed at the air bearing surface, the magnetic trailing shield partially surrounding the magnetic write pole core portion and being separated from the magnetic write pole core portion and the magnetic write pole shell portion by a non-magnetic gap layer.
