Abstract
An apparatus for optical reading or recording information on an optical disc is rotatable about an axis of rotation. The apparatus includes a carriage, an objective lens, and an objective lens holder. The carriage has a center of mass. The carriage is movable relative to a frame along a path radial to the axis of rotation. The objective lens has an optical axis. The object lens is mounted to the objective holder so that the optical axis of the objective lens is within a first distance of intersecting the center of mass of the carriage. The holder is movable relative to the carriage so as to move the objective lens along its optical axis.
