An optical pick-up apparatus has a damper (120,122) which absorbs an external shock to prevent movement or shake of an objective lens (112) and enhances a driving characteristic of the objective lens (112). The damper (120,122) connects a yoke plate (144) and an objective lens holder (114), absorbs the external shock to prevent the movement or shake of the objective lens (112), and reinforces a driving force of the objective lens (112) in the focusing and/or tracking direction(s), thereby improving the focusing and tracking characteristics of the objective lens (112). <IMAGE> |
