A magneto-optical information reproducing apparatus and method reproduces information by displacement of a domain wall of a magnetic domain recorded by mark-edge recording on a recording medium. The apparatus applies a magnetic field for reproduction, extracts a signal produced by displacement of a domain wall of one of a front edge and a rear edge of a magnetic domain, then optionally reverses the direction of the magnetic field, and extracts a signal produced by displacement of the domain wall at the other edge. The apparatus may also synthesize a signal produced by displacement of a domain wall at the front edge with a signal produced by displacement of a domain wall at the rear edge, with the synthesized signal being used as the reproduced signal.
