Abstract
An optical disk apparatus includes a carriage, a plurality of objective lens support portions, and a plurality of magnetic field generating means. The carriage is placed to oppose an optical disk and held to be reciprocally movable between an outer peripheral portion of the optical disk and its central portion. Each of the objective lens support portions has an objective lens elastically supported by an elastic member. The magnetic field generating means move each of the objective lenses in a direction perpendicular to the surface of the optical disk and a radial direction of the optical disk. Some of the magnetic field generating means which are used, in pairs, for the objective lens support portions are shared by the plurality of objective lens support portions.
