ABSTRACT:
A method for fabricating a magnetic head having multiple readers includes forming a plurality of generally laterally positioned lower shields; forming a lower gap layer above each lower shield; forming a sensor above each lower gap layer; forming an upper gap layer above each sensor; and forming an upper shield above each upper gap layer; wherein an overall gap thickness is defined between vertically aligned pairs of the upper and lower shields, wherein the overall gap thickness between one of the pairs of upper and lower shields is thicker than the overall gap thickness between another of the pairs of upper and lower shields.
