Abstract
An apparatus and associated method may be used to provide a data sensing element capable of detecting changes in magnetic states. Various embodiments of the present invention are generally directed to a magnetically responsive lamination of layers and means for generating a high magnetic moment region proximal to an air bearing surface (ABS) and a low magnetic moment region proximal to a hard magnet.
