Even though the CD drive spins at very high RPM, it seems strange that the application of ink is enough to through a drive out of balance at all, let alone enough to be a problem.
I've had a few CDs that had a hole that was a tiny bit larger than spec. The CD slipped on the spindle, chattering a little, until it spun up enough that it eventually stopped slipping. It wasn't very long- somewhere less than 5s.
Yeah, it's all kind of strange to me. In my experience, Mac Superdrives over the years have been odd ducks. For example, I've had data DVDs burned onto archival media and verified during the burning process that were unreadable on Mac Pros, but were readable of G4 Macs, and have encountered the same thing with commercial video DVDs. I think there are variations in the different DVD/CD readers/burners that Apple uses from different sources that account for this, but I'm not technically knowledgeable enough about this stuff to pinpoint what the problem is. All I know is that at work and at home, it's better to have at least a handful of optical drives of different makes and generations if you want to make sure that all your CDs and DVDs (both commercial and produced with your Mac) will all be readable.
