Abstract
An actuator (23) includes six suspension members (61) to (64), (71), and (72) that connect a bobbin (5) for holding a lens holder (2) to a suspension base (8), and an aberration-correcting element (9) mounted on the bobbin (5). One-end portions of the two lower suspension members (71) and (72) are fixed to both sides of the aberration-correcting element (9) between which the optical axis of an objective lens (1) is disposed, and the other-end portions of the suspension members (71) and (72) are fixed to both sides of the suspension base (8) spaced in the X-axis direction. First and second driving signals (S1) and (S2) are supplied to the aberration-correcting element (9) through the suspension members (71) and (72).
