<p>The present invention provides an optical pickup apparatus for reading informational signals written in a recording medium such as magneto-optical disc (1) in which a flux of reflected light from a recording medium which is irradiated with a flux of light is inclinedly incident from one side upon a flat plate like transparent member (8b; 11b; 15) having one side which is a polarization reflection surface (8c; 11c; 15a) and the other side which is a total reflection surface (8d; 11d; 15b) and fluxes of light reflected on the one side and the other side of the flat plate like transparent member (8b; 11b; 15) are detected by a photo-detecting element (9; 12; 14; 16) whereby simplification of the structure is achieved. <IMAGE></p> |
