Abstract
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.
