Title: Optical disc apparatus for installing two types of optical discs

Abstract: An optical disc apparatus has a first objective lens for a first optical disc such as a CD and a second objective lens for a second optical disc such as a DVD. The first and second objective lenses are mounted on a base that is transferrable in a direction of radii of the first and second optical discs coaxially installed in the optical disc apparatus. A first center of the first objective lens is located on a first line passing through a center of the first optical disc. On the other hand, a second center of the second objective lens is located on a second line orthogonal to the first line. The first and centers are separated from each other by a predetermined distance.
