PURPOSE:To attain highly accurate control of a track width by applying patterning with high accuracy to a width of a tip of a lower magnetic film to decide a track width and forming the width of the tip of the upper magnetic film wider than that of the lower magnetic film. CONSTITUTION:A 1st magnetic film 12, a gap film 15 and a 2nd magnetic film 13 are laminated sequentially on a base 11 and the 1st magnetic film 12 and the 2nd magnetic film 13 are overlapped at an end face opposed to a recording medium via a gap film 15. Then, the width of the layer at the end face of the 1st magnetic film 12 is formed wider than that of the 2nd magnetic film 13. Since the tip of the lower magnetic film 12 is subject to patterning on a flat face, the pattern with a small dimension variance is obtained easily and highly accurate control of the track width is attained. |
