hoi hoi folks - long ago and far away i was personally responsible for the first set of cd-r longevity tests - eventually it became a full compliance standardized process - you can learn all about it here -
http://www.osta.org/technology/cdqa.htm osta's website has a plethora of information - and information is far better than rumor
cd-r's utilize a dye layer that will breakdown over time - the type of dye used and the exposure to direct sunlight will effect the longevity - as will other things - but those 2 are the biggies
if you wish to have discs last a long time get good discs to begin with and treat them as valuable
bear in mind the cd-r's are an iso standard product - and that the federal government of the us was involved in the standards process - specifically so that they could get a product that had long life - compared to tapes - and was a standard - so that when a newer technology emerged - which will happen - that the migration to that new medium will be an easy process - remember the fear and hang wringing of systems failure of y2k - cd-r's are the 1st standard compliant media
if you buy cheap discs and treat them like a pressed disc you'll get unhappy results - sorta like nearly everything in life
fwiw when i 1st started selling cd-rs in 88 the discs were retailing for ~$300 each and the recorders where a 2 piece set that oem'ed for ~25k - and it was single speed - i still have discs from that time that are readable - today you can get blanks for pennies and a 16x recorder for less than the 1st blank disc - the point being caveat emptor
though i don't read dutch my 1st thought is of chicken little - much ado about nothing
end of rant
Thanks for the input.
FR is awesome.
It always helps to get input from people who were there and actually know what they're talking about.
Now... about that contactless multiple-laser $10k record player...
