摘要： An optical pickup apparatus for performing a reading or recording operation of information on one of different kinds of optical information recording medium, each having a transparent base board in different thickness. The optical pickup apparatus includes: a laser beam generator; a light converging optical system for converging luminous flux from the laser beam generator through the transparent base board onto an information recording surface of the optical information recording medium. In the optical pickup apparatus, the light converging optical system includes an objective lens and divides a light flux from the laser beam generator into at least two areas in a direction perpendicular to the optical axis; the different kinds of optical information recording medium includes a first optical information recording medium, having a transparent base board with a thickness t1, and a second optical information recording medium, having a transparent base board with a thickness t2; and magnification m2 of the objective lens, viewed from the second optical information recording medium, is smaller than magnification m1 of the objective lens, viewed from the first optical information recording medium side.
