ABSTRACT:
An apparatus for generating a modulated magnetic field includes a magnetic head coil and a pair of additional inductive coils. The ratio of the average inductance of the additional inductive coils to the inductance of the head coil is from 2 to 8. The apparatus ensures a magneto-optical recording system of the magnetic field modulation mode having an increased switching speed and a minimized overshoot of recording current.
