Abstract
A multi-sensor reader that includes a first sensor that has a first sensor stack, which includes a sensing layer that has a magnetization that changes according to an external magnetic field. The first sensor also includes a first seed element below the first sensor stack. The multi-sensor reader also includes a second sensor stacked over the first sensor. The second sensor includes a second sensor stack, which includes a sensing layer that has a magnetization that changes according to the external magnetic field. The second sensor also includes a second seed element below the second sensor stack. The second seed element is structurally different from the first seed element and includes a stabilization feature.
