Abstract
A magnetic shield that is capable of enhancing magnetic reading, such as in use as a data transducing head. A magnetic stack can have a read element with an air bearing surface (ABS). The read element may be positioned adjacent a shield layer with a continuously curvilinear sidewall and a shield feature may be positioned within the areal extent of the continuously curvilinear sidewall.
