Abstract
A multi-sensor reader that includes a first sensor that has a sensor stack, which includes a free layer (FL) that has a magnetization that changes according to an external magnetic field. The first sensor also includes a shielding structure that is positioned over the sensor stack. The multi-sensor reader also includes a second sensor stacked over the first sensor. The second sensor includes a sensor stack, which includes a FL that has a magnetization that changes according to the external magnetic field. The multi-sensor reader further includes an isolation layer between the first sensor and the second sensor. A FL-to-FL spacing reduction feature is included in at least one of the isolation layer or the shielding structure.
