Abstract
Various embodiments generally relate to a magnetic sensor, and more specifically to a magnetoresistive read head sensor. In one such exemplary embodiment, a magnetic sensor comprises a sensor stack and magnetic bias elements positioned adjacent opposite sides of the sensor stack. At least one of the bias elements has a non-rectangular shape, such as substantially trapezoidal or parallelogram shapes having non-perpendicular corners.
