Abstract

PURPOSE:To prevent flat spring resonance during the tracking operation of an objective lens by forming an objective lens elastic supporting member as a composite body having a soft viscoelastic member between hard elastic members. CONSTITUTION:A flat composite body 18 is constituted by interposing a rubber plate 20 of a relatively soft viscoelastic member between a couple of metallic flat springs 19 of relatively hard elastic members to obtain desired damping characteristics, and also to prevent buckling against focusing.
