Patent abstract
Embodiments in accordance with the present invention provide a Current Perpendicular to the Plane—Giant Magnetoresistive (CPP-GMR) head exhibiting a high magnetoresistance (MR) ratio with a low area-resistance product. A lower shield is made up of a first shield layer/a crystalline reset layer/a second shield layer, and an amorphous material is used in at least a part of the crystalline reset layer, thereby controlling crystallinity of the second lower shield/the CPP-GMR head.
