Patent ID: 7830759

Claim:
An objective lens drive comprising: a lens holder to which a first objective lens and a second objective lens that have different specifications are attached, the lens holder being moved at least in a focusing direction substantially parallel to optical axes of the first and second objective lenses and in a tracking direction orthogonal to the focusing direction; a support configured to movably support the lens holder at least in the focusing direction and in the tracking direction; first adjusting means, which is provided between the first objective lens and the lens holder, for adjusting a tilt of the first objective lens in a direction about an axis in a first direction that is any direction in a plane orthogonal to the focusing direction; and second adjusting means, which is provided between the second objective lens and the lens holder, for adjusting a tilt of the second objective lens in a direction about an axis in a second direction that is in a plane orthogonal to the focusing direction and is substantially orthogonal to the first direction, wherein a relative angle between the first and second objective lenses is adjusted by tilt adjustment that is made possible by the first and second adjusting means.
