Objective lens driving apparatus, for optical data recording, that corrects the focusing error and tracking error of a light spot formed on, for example, an optical disk

摘要

The objective lens holder (1) is movable in the direction of the lens's optical axis and rotatable about a rotation axis parallel to the optical axis, by the interaction of a single magnet (8) and two current carrying coils. An independent claim is also included for a method of driving an objective lens.
