摘要： 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.

摘要： An optical system supporting device in which an optical system holding member is supported by springs to be movable in focusing and tracking directions; and each of the springs has at least one portion which is oriented parallel with a tangential direction and one bending portion which is bent toward an optical axis of the optical system. Therefore, the holding member is made small in width with respect to the tracking direction; and thus the holding member can be made light in weight such that the driving sensitivity of the holding member is improved.

摘要： An apparatus for supporting an objective lens projecting a light beam upon an optical record disc having a data track recorded therein, movably in a focusing direction parallel to an optical axis of the objective lens as well as in a tracking direction perpendicular both to the optical axis and to the track in order to effect focusing and tracking servo controls, including four resilient wires arranged between a lens holder and a stationary base member, said resilient wires being not in parallel with each other. Two resilient wires provided nearer to the optical record disc are arranged such that extensions of these wires intersect with each other at a first point to make a first apex angle and the remaining two wires are arranged such that extensions of these wires intersect with each other at a second point to form a second apex angle, the first and second points being aligned in the focusing direction and the first apex angle being smaller than the second apex angle.
