<p>In one embodiment, a read sensor included an antiferromagnetic (AFM) pinning layer, the AFM pinning layer being recessed from a media-facing surface in an element height direction to a first height, a first antiparallel pinned multilayer (API) positioned above the AFM pinning layer and extending beyond the first height to the media-facing surface, a second antiparallel pinned layer (AP2) positioned above the AP1 and extending beyond the first height to the media-facing surface, and a free layer positioned at the media-facing surface above the AP2 and extending from the media-facing surface in the element height direction to a second height, wherein the element height direction is perpendicular to the media-facing surface, wherein the AP1 and the AP2 are not recessed from the media-facing surface, and wherein the AFM, and AP1, and the AP2 extend beyond the free layer in the element height direction beyond the second height.</p> |
