摘要：
A magnetic sensor has at least a free sub-stack, a reference sub-stack and a front shield. The free sub-stack has a magnetization direction substantially perpendicular to the planar orientation of the layer and extends to an air bearing surface. The reference sub-stack has a magnetization direction substantially perpendicular to the magnetization direction of the free sub-stack. The reference sub-stack is recessed from the air bearing surface and a front shield is positioned between the reference sub-stack and the air bearing surface.
