Abstract
There is disclosed a magneto-optical information reproducing apparatus which can perform information reproducing with a low crosstalk level, and the apparatus comprises a biasing electromagnet 19 for generating a reproducing magnetic field, and an MPU 26 for adjusting an intensity of the magnetic field generated by the biasing electromagnet 19 with respect to a land and a groove so that with respect to one of the land and the groove in which reproducing object information is recorded, a level of a crosstalk attributed to the information recorded in the other one of the land and the groove is lowered.
