Green Beam
what advantage is realize by use of a short wavelength light beam (Green versus Red)?
Compact disc recording media uses laser to read back the information that they contain, what advantage is realize by use of a short wavelength light beam (Green versus Red).
That would only work if the light frequency is used as the carrier. It is not. Regardless of using a red or green laser you would still get 1 bit per pulse and the amount of data transfered is dependant on the speed of laser modulation and not on the wavelength of the laser.
I would assume that a shorter wavelength would actually mean a higher density of information on the storage medium and not necessarily higher transfer rates.
Edit:.. Bah.. InPhase E beat me to it.
