Abstract
Disclosed is an optical pickup device which is small, light, and thin and which is equipped with a tilt adjusting mechanism. A lens holding body holding an objective lens and a support body supporting the lens holding body so as to allow the lens holding body to move in the focusing direction and/or the tracking direction of the objective lens, are supported at two support points on a support body mounting surface of an optical base so as to be rotatable around an axis extending in a tangential direction of an optical disk.
Claims15
An optical pickup device comprising:
- an objective lens for condensing a light beam on an optical disk;
- a lens holding body for holding the objective lens;
- a support body for supporting the lens holding body so as to allow the lens holding body to move in at least one of a focusing direction and a tracking direction of the objective lens;
- and
- an optical base which is capable of moving in a radial direction of the optical disk and which holds the support body so as to allow the support body to rotate around a rotation axis perpendicular to the focusing direction and the tracking direction.
