ABSTRACT:
Disclosed is a photo-magnetic reproducing apparatus in which an incident light beam polarized in a predetermined direction enters a recording medium on which information is magnetically recorded. The light beam from the recording medium is split into two light beams, and a signal containing the information therein is detected from one of the split light beams, while a signal not containing the information therein is detected from the other of the split light beams. The detected two signals are differentiated to thereby obtain an information reproducing signal.
