<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin-film magnetic head, highly accurately forming an upper shield layer to be flat without adversely affecting a read element or the like, and a thin-film magnetic head wherein an upper shield layer is formed flat to reduce noise of an output signal. <P>SOLUTION: A hard bias film 12 is formed so that the outer edge 12a of the hard bias film 12 in a surface direction protrudes from the outer edge 16a of an upper shield layer 16 in a surface direction. After the formation of the upper shield layer 16, the part of the hard bias layer 12 protruded from the outer edge 16a of the upper shield layer 16 in the surface direction is removed by etching using the upper shield layer 16 as a mask. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
