ABSTRACT:
An optical pick-up apparatus has a damper which absorbs an external shock to prevent movement or shake of an objective lens and enhances a driving characteristic of the objective lens. The damper connects a yoke plate and an objective lens holder, absorbs the external shock to prevent the movement or shake of the objective lens, and reinforces a driving force of the objective lens in the focusing and/or tracking direction(s), thereby improving the focusing and tracking characteristics of the objective lens.
