Abstract: The present invention provides a thin film write head having an upper and lower pole structures and conductor turns forming a winding for generating magnetic flux. The conductor is formed with a non-planar top surface. The winding of the present invention may be formed of lower and upper turns. The upper turns may be formed with a non-planar top surface, a non-planar bottom surface, or both. It is preferred that the bottom surface of the upper conductor turns be coherent with the non-planar top surface of the lower conductor turns. The non-planar top surface may be formed by removing corners formed during deposition between a generally planar top surface and abutting side walls. The corners may be removed by ion milling to form the non-planar top surface. The conductor may be copper with the non-planar top surface having sloping facets. The thin film write head of the present invention may be utilized to provide an improved data storage and retrieval apparatus.
