Abstract
A data reader may be configured at least with a magnetic stack that has a first magnetic layer separated from a second magnetic layer by a non-magnetic spacer layer. The first magnetic layer may have an areal extent on an air bearing surface (ABS) that differs from the second magnetic layer while the second magnetic layer can be configured with a first plurality of linear sidewalls that are each angled with respect to a second plurality of linear sidewalls of the first magnetic layer.
