Abstract
An optical storage device including a carriage movable in the radial direction of an optical storage medium, a light source, a first lens fixed to the carriage for focusing a light beam emitted from the light source onto the optical storage medium, a second lens interposed between the first lens and the light source, a beam splitter for reflecting at least a part of the light beam transmitted through the second lens in a direction perpendicular to the optical storage medium, and an actuator for supporting the second lens so that the second lens is movable in a given direction. The actuator includes an actuator base fixed to the carriage, a lens holder for holding the second lens so that the optical axis of the second lens extends in a direction substantially parallel to the optical storage medium, a supporting mechanism for movably supporting the lens holder to the actuator base, and a driving mechanism for moving the second lens in the above given direction.
