Abstract:
1. A method for fabricating a magnetic head comprising: fabricating a plurality of thin film layers to create a read sensor, said read sensor including a first insulation (G milling said plurality of thin films such that a central sensor region is protected from milling and unprotected outer regions are milled down to said G fabricating a hard bias structure upon said G depositing said seed layer upon said G removing an upper portion of said seed layer to create an upper surface of said seed layer; depositing hard bias material upon said upper surface of said seed layer to create said hard bias layer that is disposed upon said seed layer; and wherein said hard bias layer has a midplane that is disposed at a horizontal level within the magnetic head that is approximately coplanar with said midplane of said free magnetic layer.
