An optical pickup apparatus couples light beams, and corrects a chromatic aberration and a spherical aberration. A coupling lens includes groups of lenses common to the light sources so as to converge a light beam from each of the light sources. An aperture changes an aperture diameter for the light beam, which has been converged by the coupling lens, in accordance with one of the light sources from which the light beam is emitted. An objective lens converges the light beam onto a recording surface of one of the optical information recording media corresponding to the one of the light sources that emits the light beam. A lens moving mechanism moves at least one group of lenses from among the groups of lenses of the coupling lens in a direction of an optical axis thereof in accordance with an aperture diameter of the aperture.
