A quick technical question for those of you out in net.land:--

What is the frequency or wavelength of the light produced by the lasers
in CD players??  I suspect it is either IR around 850 nm or in the
red region around 650 nm, but was curious to know for sure.

Also does anyone have the reference to the original Phillips Tech Review
articles describing the CD system.  I seem to have misplaced mine when
I moved.

Thanx,

Bill Mitchell
