This is how the disc reads 1's and 0's on the disc, which is Binary format the computer can read. ~%~%~%~%~% REFLECTION ~%~%~%~%~% When light hits a pit is is generally scattered, but when light hits a land it will reflect back to the detector, where it will pass through a prism that deflects the reflected laster beam to a light-sensing diode. ~%~%~%~ VOLTAGE ~%~%~%~ The pulse of light that strikes, and the electrical pulse determines weither it is a 1 or a 0, the length is determined by the timing circuit on the CDROM. ¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬ NemesisEra Copyright ©2001-2002 "Project:Zero" ­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬­¬
