Urgent! What are these lines?

[Flamefury8]

I was playin SMG for a while and decided to play Wii Sports. So I eject the SMG disk and to my surprise there were the "circlely" lines around the disk. Is this normal?

im not sure what those lines are but, as long as SMG still works i think you'll be fine.
