The present invention provides an optical pickup apparatus to for recording and/or reproducing information on an optical information recording medium including multilayered information recording surfaces. The optical pickup apparatus includes: a light source; an objective lens; a first optical element including a first optical area and a second optical area; a second optical element including a third optical area and a fourth optical area. The optical pickup apparatus further includes a light-converging element for receiving a main light flux from one information recording surface and a secondary light flux from another information recording surface and converging the main light flux at a position between the first optical element and the second optical element. The optical pickup apparatus further includes a polarization splitting optical member for splitting the main light flux and the secondary light flux; and a photodetector for receiving the main light flux.
