Zusammenfassung:	PCT No. PCT/US96/08348 Sec. 371 Date Apr. 4, 1997 Sec. 102(e) Date Apr. 4, 1997 PCT Filed Jun. 3, 1996 PCT Pub. No. WO96/41336 PCT Pub. Date Dec. 19, 1996A thin-film head has patterned pole tips (68) and a smooth interface topography (70) which eliminates the accumulation of foreign material around the pole tips (68). The patterned pole tips (68) are formed by removing material to obtain a desired pole tip shape. Fill material is added and reduced to produce a smooth surface topography (70).
