This guy is a moron.
Only on a CD-R with a bare foil exposed, AND using an extremely acidic marker, AND waiting several years for it to react, would such a thing occur.
Did anybody else notice how he totally ignored the question about labels, and went onto this tirade about markers?
And then it is called "inkjet media". He referred to it as "white surface" media.
I don't think this guy has ever even burned a disc, much less have qualifications to answer questions about the technology. All he does is spout myth in print.
I hate, hate, hate, hate, hate misinformation. Especially the really stupid myths.
