Older CD-R media did not have a protective plastic coating over the dye layer.
AND the dye layer was highly susceptible to ambient or sustained light, even of low levels. You literally could hold a CD to the sun for a few minutes....and ruin it.
Bear in mind that the CD itself is made of plastic. Nothing too esoteric here. Its plastic. Cost for a CD-R these days is down to about 26 cents American.
Today's CD dye layer is much hardier, and has a much longer archival life whether stored in paper sleeves, jewel cases or vinyl sleeves. (I personally don't like vinyl sleeves, because the CD tends to "stick".
Under NO circumstances use CD-RW for archival purposes. They cost more, last less long, and will, one day, no longer verify.
There is quite a lot of scientific information about CD technology on the www when/if you are interested.
BTW I use ONLY FujiFilm CD-R 700/80, and have never had a failure, and archive thousands of images for years, quite successfully.
