Abstract
An electromagnetic objective lens driving apparatus of an optical disc data recording and reproducing apparatus includes a carriage which is movable in a radial direction of an optical disc, and an objective lens holder which supports an objective lens in a manner such that laser beams are converged onto the optical disc. The objective lens holder is supported on the carriage so as to move in the focusing and the tracking directions of the optical disc. The objective lens holder is provided with a cylindrical holder portion which holds the objective lens, and a pair of symmetrical wings that project radially from the cylindrical holder portion in the tracking direction.
