<< you could unbalance the CD and it will cause your drive to vibrate when it reads >>
Have you guys ever seen those thin metal theft protection strips that Blockbuster used to put on their DVDs? Apparently it did cause the discs too be heavier on one side, which caused damage to either the disc or the player. Now they don't do that anymore. Maybe they were afraid of another lawsuit. I doubt seriously though, that too much ink on one side could have the same effect. What could ink possibly weigh?
