Abstract
Cross talk levels of -20.8 dB for double-density tracks on compact disk-RW (CD-RW) media are demonstrated by using quadrant pupil detection (QPD) signal cancellation with a single focused spot. Cross talk cancellation in a single optical beam systems by means of a quadrant cell detector is analyzed. Results indicate that cross talk arising from single-tone frequency patterns can be corrected by simple amplitude and phase scaling, while dual-tone cross talk cancellation may require the use of shading bands.
