ABSTRACT:
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.
