ABSTRACT:
In an objective lens driving device for an optical disk, a plurality of elastic supporting members supporting an objective lens have bent portions bent approximately in the focus direction and are arranged in parallel approximately in the focus direction to cause expansion/contraction of the elastic supporting members in the direction offsetting a moment M. With this structure, a tilt correction method of the movable portion, a tilt correction method of an objective lens for an optical disk, and an objective lens driving device for an optical disk can be provided capable of reducing the size of the movable portion, minimizing tilt of the objective lens in the focus direction to provide enhanced optical performance, and restraining a resonance peak by the elastic supporting members.
