Optical recording systems include a transparent layer between the diffraction-limited objective and the recording surface, which prevents dust and dirt from obscuring the optical signal. A laser beam focused on the recording surface may be aberrated by thickness variations or birefringence in this cover sheet. This paper presents calculations of these aberrations and a discussion of the corresponding cover-sheet tolerances.
