Abstract: PROBLEM TO BE SOLVED: To provide a thin film signal magnetic pole magnetic recording head high in recording sensitivity and easy in production. SOLUTION: This thin film signal magnetic pole magnetic recording head is composed of a main pole thin film 5 of a soft magnetic thin film, thin film conductor coils 3 and 6, and a magnetic core (2 and 7) of prescribed soft magnetic materials, and has at least two or more sets of the loop-shaped spiral shape thin film conductor coil whose number of turns >=1 ternes. These thin film conductors coils 3 and 6 are disposed on both sides in the film thickness direction of the main pole thin film 5, and are formed so that two thin film conductor coils 3 and 6 disposed between the both sides in the film thickness direction of the main pole thin film 5 are connected or not connected to each other at one place by using the conventional technique. Consequently, the front end of the main pole film is excited, then the magnetic head excellent in recording sensitivity and hardly being affected by the external magnetic field is easily manufactured.
