METHOD FOR CORRECTING INCLINATION OF MOVABLE MEMBER, METHOD FOR CORRECTING INCLINATION OF OBJECTIVE LENS FOR OPTICAL DISK, AND DEVICE FOR DRIVING OBJECTIVE LENS FOR OPTICAL DISK

摘要

PROBLEM TO BE SOLVED: To provide an inclination correction method for a movable member, an inclination correction method for an objective lens for an optical disk, and an objective lens driving device for an optical disk, by which optical performance is improved by suppressing as much as possible the inclination in the focus direction of an objective lens while movable members are miniaturized and resonance peak can also be suppressed small by using elastic supporting members.;SOLUTION: A plurality of elastic supporting members 3 for supporting the objective lens 1 are provided with a bent part 3c bent nearly in the focus direction, and are arranged in an array nearly in the focus direction so that expansion and contraction of the elastic supporting members 3 act in a direction canceling the moment M.;COPYRIGHT: (C)2002,JPO
