PURPOSE:To set the sensitivity of a magneto-optical recording medium and to record it at a high speed and with high density by generating large magnetic field without increasing the winding number of a winding wire and with small inductance as it is. CONSTITUTION:A magnetic head is constituted of a magnetic yoke 1 and plural number if winding wires C1, C2, C3, C4 and is provided with the driving circuits T1, T2, T3, T4 of the same number as the number of the winding wires driving respective winding wires independently. Thus, by providing plural winding wires and plural driving circuits driving respective winding wires, large magnetic field is generated entirely while suppressing the increase of the inductance of respective winding wires and high speed magnetic field modulation for obtaining high recording density and a high speed transferring rate characteristic is obtained.
