摘要： A magnetic reader comprises first and second shields oriented transversely to a media-facing surface, a magnetoresistive stack located between the first and second shields, and a flux guide. The magnetoresistive stack extends from a proximal end oriented toward the media-facing surface to a distal end oriented away from the media-facing surface. The flux guide extends from the first shield toward the second shield, and is spaced from the magnetoresistive stack at the distal end. The flux guide magnetically couples the distal end of the magnetoresistive stack to the first shield.

摘要： A magnetoresistive sensor having a trilayer sensor stack with two ferromagnetic freelayers separated by a nonmagnetic spacer layer is disclosed. The sensor is biased with a back biasing magnet adjacent a back of the trilayer sensor. The back biasing magnet, the trilayer sensor stack, or both have substantially trapezoidal shapes to enhance the biasing field and to minimize noise. In some embodiments, the trilayer sensor or back bias magnet have a shape designed to stabilize a micromagnetic “C” shape or concentrate magnetic flux in the trilayer sensor stack.
