Magneto-optical devices for recording and reproducing comprise an electromagnet which reverses the magnetization of the magneto-optical layer of the magneto-optical disk in function of the bits to be stored. To ensure rapid and reliable reversal of the magnetic field, a series circuit consisting of...
