Hi, folks. I think I have noticed circular scratchs on my game disks. I cannot see them in normal light, but when I shine a torch or a light on it, I see large and small circles on my discs. I've heard that those circles are not scraches caused by XBOX, but they're marks from manufacturing process, and most of XBOX game discs (if not all) have those circles if looked hard enough. Could anyone clarify this please ?? P.S. I know this is different from Japanese XBOX disc scratch happening. Their scratch were tiny dust-like scratches on edge of discs.
