A thin-film type electromagnetic transducer formed on a nonmagnetic substrate by a thin-film forming process. The transducer includes a magnetic core formed on the substrate by the thin-film forming process, and a conductor coil formed on the substrate by the thin-film forming process, so as to be wound around the core. The core is shaped so that a leakage flux generated along the plane of the substrate is greater than that generated in a direction intersecting with the plane of the substrate, the leakage fluxes being generated from the core when a current is supplied to the coil. In a method for transferring signals from the thin-film type electromagnetic transducer described above, a magnetic head is located so as to face that region of the core of the transducer where the maximum leakage flux is generated. The magnetic head has a magnetic gap such that the direction of a leakage flux generated in the gap is coincident with that of the maximum leakage flux from the core, and whereby magnetic signals are transferred between the magnetic head and the maximum-leakage-flux generating region of the core.
