ABSTRACT:
An objective lens drive/support mechanism in an optical disc player system includes an objective lens support member which is slidably and rotatably secured to a main shaft of the mechanism. An objective lens is supported by the objective lens support member at a position which is separated from the main shaft by a predetermined distance. The objective lens support member is driven to slide along the main shaft to perform the focus control, and the objective lens support member is rotated around the main shaft to perform the tracking operation. A symmetrically "8" shaped elastic damping member is tightly secured to the main shaft at the center of the symmetrically "8" shaped elastic damping member. Both ends of the symmetrically "8" shaped elastic damping member are fixed to the objective lens support member, whereby the single symmetrically "8" shaped elastic damping member conducts the damping operation in both the focal direction and the tracking direction.
