Abstract
In trying to explain the colored line on a CD or DVD under the skimming light rays of a white lamp,1 we made errors that affect the equations but not the overall conclusions. The mistakes stem from Eq. (1) of Ref. 1. As seen in Fig. 1, in which two parallel light rays coming from the source S reflect from point P and P0 on the CD (or DVD), the total length of the path from S to O is. (Figure Presented) (Formula Presented).File in questo prodotto:
