I've had that with DVD-RWs, right after taking them new from the spindle without ever using them before. It's a manufacturing problem, but it doesn't always seem to affect how well they work. These were with Verbatim discs which are literally the best quality discs you can buy.

Good to know about the marker being confirmed to cause damage, it's not just a myth.
