Abstract:
A combined magnetic read and write head having a top, a bottom, a front and rear ends and an air bearing surface (ABS) at the front end, comprising:a substrate;first and second shield layers on the substrate, the second shield layer having a top surface;a read gap separating the first and second shield layers;a sensor layer with first and second sensor leads positioned in the read gap;a planarization layer on the substrate substantially surrounding the first and second shield layers, a top surface of the planarization layer being substantially coplanar with the top surface of the second shield layer and forming a planar surface;first and second pole pieces on the second shield layer;a write gap;the first and second pole pieces being separated by the write gap at the ABS and connected at a back gap that is recessed in the head from the ABS;at least one coil layer being located on the planar surface, a portion of the coil layer being located between the first and second pole pieces; andat least a first write lead and first and second read leads located on the planarization layer.
