ABSTRACT:
An optical-pickup apparatus includes first and second objective lenses that focus first and second laser light on information-recording layers of first and second optical discs, 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 and second objective lenses in an adjacent manner, a disc surface of the first optical disc and of the second optical disc being substantially parallel to confronting faces of the first and second objective lenses, that confront the disc surface, a minimum distance between the disc surface and the confronting faces in a direction of an optical axis of the turntable being greater than a thickness of the turntable in a direction of a rotation axis of the turntable, either one or both of the first and second objective lenses configured to focus bluish-violet laser light on an optical disc.
