[Dixielandjazz] CD-Rs with short memory...

I just came across these news:

"[...]an investigation by a Dutch personal computer magazine, PC Active,
has shown that some CD-Rs are unreadable in as little as two years,
because the dyes in the CD's recording layer fade. These dyes replace the
aluminium "pits" of a music CD or CD-Rom, and the laser uses that layer to
distinguish 0s from 1s. When the CD is written, the writing laser "burns"
the dye, which becomes dark, to represent a "1" while a "0" will be left
blank so that if the dye fades, there's no difference; it's just a long
string of nothing to the playback laser."


So for all you guys entrusting your priceless LPs to CD - hang on to
the originals
