ABSTRACT:
In an optical disc apparatus for recording and/or reproducing data on an optical disc, a lens holder for holding an objective lens is dynamically moved not only in a direction perpendicular to a data recording face of an optical disc but also in a direction parallel to the data recording face and crossing substantially at right angle with data recording tracks on the data recording face when the optical disc is loaded on the optical disc apparatus so as to remove the sticking of the movement of the objective lens due to adhesion of dust, break or deformation of the components.
