Abstract

PURPOSE: To obtain an effective driving range of high sensitivity throughout a wide range by laminating a sheet-shaped elastic member and damping members to form a flat spring supporting an objective lens and providing a hollow part in the center.
CONSTITUTION: An objective lens supporting member 2 is supported displacably by a pair of flat springs 4a and 4b for focusing, a relay member 5, and a pair of flat springs 6a and 6b for tracking. Each of these flat spring members is structured by laminating sheet-shaped elastic members 20 and 21 of high rigidity and a sheet-shaped damping member 22 having a high damping characteristic, and aperture parts 20a and 21a of the hollow part are formed in the center. Thus, resonance is attenuated by the damping member 22, and the effective driving range of high sensitivity is obtained throughout a wide range by elastic members 20 and 21 of high rigidity and the hollow part.
