ABSTRACT:
An aberration correcting mechanism includes a corrective optical glass for correcting a spherical aberration and a link mechanism for movably supporting the corrective optical glass. The corrective optical glass is a parallel, flat plate having the same refractive index as that of a cover glass of a disk, and its length is slightly greater than the moving distance of an objective. The link mechanism has first and second links. While one end of each of the links is rotatably attached to its corresponding end portion of the corrective optical glass, the other ends of the links are rotatably mounted on the mounting portions on a deck base. The link mechanism also has a third link and a solenoid, and one end of the third link is rotatably attached to the central portion of the second link, while the other end of the third link is rotatably attached to the solenoid. The solenoid is fixed to a fixed portion on the deck base.
