摘要:
An optical disc of one embodiment of the invention is disclosed that includes a first surface, a second surface, an optically writable label area, and an optically writable data area. The first and the second surfaces are oppositely situated to one another. The label area is on one of the first and the second surfaces. The data area is on one of the first and the second surfaces. The mechanism aids proper focusing of an optical beam of an optical disc device on the optically writable label area and on the optically writable data area.
