ABSTRACT:
A compact write element includes a conductive shield layer, an insulating write gap layer, a pole pedestal, a coil, and a conductive pole layer, and, in some embodiments also includes a backgap. The pole pedestal and the coil, and, in some embodiments the backgap, constitute a self-aligned array of components that may be formed in a single masking operation to allow for very tight tolerances between the components for a shorter yoke length. The pole layer is substantially flat and parallel to the conductive shield layer, providing for a shorter stack height. Also, a compact MR read/write head includes such a write element and a magnetic data storage and retrieval system includes the compact MR read/write head having such a write element.
