.. I have seen first hand the damage done by Sharpies on both commercial CD's and CD-R's, rendering them unplayable after the lacquer was eaten through when the disc's were labeled with the marker.
The aluminum layer directly under the ink was damaged, and the disc was unplayable and unrecoverable in terms of data.
This was seen in several instances, but to be fair, most of them were found from disc's that had been in a car, in the deep south, so heat and humidity were in play here. There at least two that had been kept inside, and not exposed to automotive conditions, but these were also not as badly damaged.
But hey, what's the difference if only 5% of the disc is eaten or 15%, it's still toast.
These problems didn't occur at first, but after a few years from the time of marking the CD's. Other CD's in the same environments did not have any problems.
I have also seen data CD-R's that had been written on with Sharpies and other brands of markers go bad after storage of 5, 7 and 10 years under "archival" conditions.
I would say you've been very lucky, and I recommend that other's shouldn't take the risk, especially when the highly recommended DIY green pen is a Uni-Posca water based ink (Uni-Posca #63833 I believe).
