My question refers to the use of printers on the top surface of CDR's, whether that surface is a white coating or, in the case of MAM-A Gold Archive discs, some of which do not have any additional coating. Is there any likelihood of those surfaces being compromised (long term) when printed on.
As for the labels that were used at the insistence of our head of cataloging, they were placed at the outside edge of the disc and were approximately 1/2 inch wide. Not only did they ruin the balance of the disc, when people inserted them into CD changers, the labels would start to peel as the slots on some of those machines were very narrow. Occasionally the reflective surface of the disc would peel as well. Sometimes when the labels peeled, one could see that the glue from the label had left tiny pits in the reflective surface of the disc. The library bought some machine that supposedly would "re coat" the discs. In some instances they would play one or two more times.
And while we are on the subject...is there any pen or marker that is "safe" for CDRs?

I think most of us understood implicitly that the subject was paper stick-on printable labels the full size of the disc. There was never any question in my mind, and they were a hassle and a problem in the early CD/DVD burning years.
When white printable CDs/DVDs came along and inexpoensive printers, it all got so much better!
But then I am an audio engineer, not a librarian, so no confusion for me.
