Abstract
PURPOSE: To obtain a good recording characteristic with a low power and obtain a thin film magnetic head where chiping dependent upon contact slide between the magnetic head and a magnetic medium is small, by providing a conductive layer, which becomes a coil, on the groove on a magnetic material substrate where a nonmagnetic material is filled.
CONSTITUTION: Ferromagnetic material layer 24 is caused to adhere to a part from contact face 23 for a magnetic recording material to groove 22 on magnetic material substrate 21 where groove 22 is formed, and a nonmagnetic insulating material is filled in groove 22 to form mold layer 26. Next, a nonmagnetic material conductor layer is caused to adhere to layer 26, and this layer is selectively removed to form coil 27 of a spiral pattern, and after that, insulating layers 28 of the same thickness as coil 27 are formed between coils 27 and between coil 27 and ferromagnetic material layer 24, and further, insulating layer 29 is formed on layers 28 to eliminate steps for ferromagnetic material layer 24. Next, after forming insulating layer 30 for constituting gap G, magnetic material layer 25 is formed on layer 30, and protection layer 31 and protection substrate 32 are provided on layer 25 and are made into one body, thereby obtaining a magnetic head.
