ABSTRACT:
A magnetic field generation device generates a magnetic field modulated according to an information signal by switching the direction of a current to be supplied to a magnetic field generation coil of a magnetic head, according to the information signal. The device is provided with a magnetic field generation core, the magnetic field generation coil, an acceleration coil and a driving device. The magnetic field generation coil is wound around the magnetic field generation core. The acceleration coil is connected in parallel with the magnetic field generation coil to shorten a current inversion time upon generation of a magnetic field.
