PURPOSE:To facilitate the process of manufacture by forming a trailing-side magnetic pole of a thin film on a bulk substrate, and sticking the trailing-side magnetic pole to a leading-side magnetic pole and thus generating a recording magnetic field which has an intenser vertical component. CONSTITUTION:The trailing-side magnetic pole 41 is formed on the bulk substrate 42 by using a high magnetic permeability thin film of a soft magnetic material such as ''Permalloy ''. The substrate 42 uses ferrite or a nonmagnetic material. Then, 45 is the leading-side magnetic pole and the bulk substrate of ferrite. Further, 46 is a stuck part and a recording medium moves to left on the paper surface. |
