Abstract
A magnetic element is generally provided that can be implemented as a transducing head. Various embodiments may configure a magnetic stack to be separated from a side shield lamination on an air bearing surface (ABS). The side shield lamination can be constructed to have a plurality of magnetic and non-magnetic layers each coupled to a top shield.

An apparatus comprising a magnetic stack separated from a side shield lamination on an air bearing surface (ABS), the side shield lamination having a plurality of magnetic and non-magnetic sub-layers each coupled to different portions of a top shield, the magnetic and non-magnetic sub-layers having linear sidewalls aligned with a longitudinal axis of the magnetic stack and configured with a shape that forms closed magnetic flux loops with the top shield.
A magnetic element comprising a magnetic stack disposed between first and second side shield laminations on an air bearing surface (ABS), each side shield lamination having a plurality of magnetic and non-magnetic sub-layers each coupled to different portions of a top shield, the magnetic and non-magnetic sub-layers having linear sidewalls aligned with a longitudinal axis of the magnetic stack and configured with a shape that forms closed magnetic flux loops with the top shield.
