摘要：
A magneto-optical information reproducing apparatus includes a device for applying a light beam polarized in a predetermined direction to a recording medium on which information is magnetically recorded, a first divider for dividing the reflected or transmitted light beam from the medium modulated into a polarized state in conformity with the information by magneto-optical effect into two light beams polarized in directions orthogonal to each other, the first divider being disposed so that the directions of polarization of the divided two light beams form an angle of 45.degree. with respect to the predetermined direction of polarization of the applied light beam, and a detector for detecting the divided two light beams.
