<p>A data storage device may be constructed to sense data bits with at least a magnetic stack contacting a shield that has a horizontal lamination of magnetic and non-magnetic layers. The magnetic layer may be configured with a first width at an air bearing surface (ABS) that defines a first aspect ratio and a different second width that defines a different second aspect ratio distal the ABS. The composite shield can increase magnetic field robustness by allowing the magnetic layer to be tuned for size, material, and shape without degrading thermo mechanical performance of the data storage device.</p> |
