ABSTRACT:
A magnetic head includes a first, second and third magnetic core of a soft magnetic film formed by a thin film forming method. One end of the first and second magnetic core face a magnetic recording medium and are disposed with a predetermined distance therebetween. The third magnetic core is disposed between the first and second magnetic cores. A conductive coil is wound around the third magnetic core. A conductive wire passes through the third magnetic core and is insulated therefrom. A DC-biased high-frequency constant current flows through the conductive wire to reproduce information recorded on the magnetic recording medium. Also, a recording signal is applied to the conductive coil.
