Abstract
A magnetoresistive sensor is generally disclosed. Various embodiments of a sensor can have at least a trilayer sensor stack 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.
