PROBLEM TO BE SOLVED: To improve high-frequency reproduction output characteristics by minimizing the recording pole width and realizing high surface recording density. SOLUTION: The base 1 supports an induction magnetic transducer element 2. The induction magnetic transducer element 2 includes an magnetic circuit consisting of an upper magnetic film 23, a gap film 22, and coil films 241, 242. The lower magnetic film 21 has a lower pole 211. The upper magnetic film 23 has an upper pole 231 facing the lower pole 211 via the gap film 22. The upper pole 231 is formed by projecting a part of the lower surface of the upper magnetic film 23. COPYRIGHT: (C)2004,JPO
