Abstract:
An optical pickup apparatus including a first objective lens that focuses first laser light on an information recording layer of a first optical disc in a first mounting state where the first optical disc is mounted on a turntable; a second objective lens that focuses second laser light on an information recording layer of a second optical disc in a second mounting state where the second optical disc is mounted on the turntable, the second optical disc having an information recording format different from that of the first optical disc; and a lens holder that integrally holds the first objective lens and the second objective lens in an adjacent manner on the outside and inside, respectively, along a radial direction of the first optical disc in the first mounting state and of the second optical disc in the second mounting state.
