Abstract: A method of one embodiment of the invention is disclosed that is for a track of an optically writable label region of an optical disc having a non-integer number of pixel positions around the track, such that a last fractional pixel position is defined. The method determines whether the size of the last fractional pixel position is greater than a fractional threshold. In response to determining that the size of the last fractional pixel position is greater than the fractional threshold, the method writes a complete pixel to the last fractional pixel position, such that the complete pixel written overlaps onto a first complete pixel position of the track.

Abstract: An optical pickup device has a semiconductor in which 2 light emitters laser emitting laser beams having different wavelengths for a DVD and CD are mounted on one package and disposes optical-system lenses with reference to a main beam for a DVD such that a long axis of an elliptic beam which is emitted from each light emitter for a CD and DVD and irradiated onto a disc is tilted at about 35° to the radius direction of a disc. This prevents an aberration from being generated in a converging spot at the DVD side due to image height and exhibits sufficient performance of lens to keep all CT, MTF and jitter in comparatively favorable conditions.
