Abstract:
In one embodiment, a magnetic head includes a lower magnetic shield layer positioned at a media-facing surface, a pinned layer positioned above the lower magnetic shield layer at the media-facing surface, at least two MR elements extending in an element height direction by a first length positioned above the pinned layer and separated in a cross-track direction by an inner layer, bias layers extending in the element height direction by a second length positioned on outside edges of the MR elements and the pinned layer, and current paths positioned above and in electrical communication with the bias layers on either side of the inner layer, each current path extending in the element height direction away from the media-facing surface by a third length.
