An optical pickup apparatus comprising: an objective lens configured to apply a laser beam for recording or reproducing information to a plurality of layers of information recording surfaces selectively, the plurality of layers of information recording surfaces being included in an optical disc mounted on a turn table; and a spherical aberration correction lens configured to be movable on a light path on the side where the laser beam is incident on the objective lens, so as to correct spherical aberration when the laser beam is applied from the objective lens to any one of the plurality of information recording surfaces in the optical disc, a distance between the spherical aberration correction lens and the objective lens on each light path when the laser beam is focused on each of the plurality of layers of information recording surfaces in the optical disc with movement of the spherical aberration correction lens, including a distance at which optical magnification of an optical system including the spherical aberration correction lens and the objective lens is maintained substantially constant.
