Abstract
An optical read/write head for a magnetic-optic recording and reproducing unit having a beam splitter placed between a collimator lens and an objective lens. The optical path of the beam reflected by a recording disk is bent by the beam splitter and the beam strikes a polarizing beam splitter. The polarizing beam splitter splits the reflected beam into P and S polarized components whose optical axes form n angel of less than 90.degree.. The rays of the P and S polarized components strike respective light detecting elements and which are co-arranged on substantially the same surface.
