-----------------------
Actually CDRs are much less reflective than 'pressed' CDs and as
such some older CD players don't have the laser power needed to
get a good (reflected) signal.
** CDRs use the same metallised ( Gold or Silver) reflecting layer
as a normal CD.
Yes. The difference is in the construction of the non-refecting
areas.
** Shame how that admission completely removes your original claim.
I didn't think that you were going to split hairs.
** And I'm not.
In a
CD they're pressed into the refecting later and become 'pits'
** Pits come first, reflective metallisation comes afterwards.
The whole game is wavelength dependant.
Perhaps with blu-ray it is but not so much with CDs as the dark and
light areas are large enough for any wavelength to read you moron.
** Pressed CDs do not have dark and light areas.
The pits are exactly 1/4 wave deep the 780nm IR wavelength used - the
IR laser light travels and extra half wavelength causing self
cancellation.
Go look it up.
All good I'll take your word for it.
** So you never had a clue how CDs work ?
So it's even more 'black-and-white'
w/r/t reflections than I thought with a pressed CD.
** Wot a desperate bull**** artist you are.
whereas with a
CDR a dye layer between the reflecting area and the pickup laser is
'burned' changing it's reflectivity index.
** The dye simply becomes opaque.
Which is a ****wit way of saying it's reflectivity index or ability
to transmit light has changed.
** Remember posting this?
" Actually CDRs are much less reflective than 'pressed' CDs and as
such some
older CD players don't have the laser power needed to get a good
(reflected)
signal. "
Yep, and I stand by it.
** You are standing on quicksand - pal.
Notice I said "CDRs..." and not 'the metallised
layer inside CRDs...'?
** Shame how nothing else is reflective.
Wot a bull****ter.
** The one being obnoxious here is you - pal.
Not exactly true but,
** It is precisely the truth.
Fact is, you have no interest in the truth.
