Abstract:
A multi-sensor reader includes first and second read sensors. The first read sensor includes a first sensor stack including a sensing layer having a magnetization that changes according to an external magnetic field, and a first biasing component configured to magnetically bias the sensing layer of the first sensor stack in a first direction. The second read sensor includes a second sensor stack including a sensing layer having a magnetization that changes according to an external magnetic field, and a second biasing component configured to magnetically bias the sensing layer of the second sensor stack in a second direction that is substantially opposite the first direction.
