Default Is my DVD-RW ruined?

I forgot about this until a few minutes ago when I was erasing my DVD-RWs. Awhile back I had some files on one of my DVD-RWs. I wanted to remove something so I booted up Nero to see if that were possible. I was surprised to see that Nero permitted the erase. When I took the disc out I looked at the back and noticed a burn like mark on the edge of the disc. Later on I decided to erase the whole thing and had Nero do a full erase (physical erase). The mark is still there. If I want to use the disc in the future will that hamper my doing so? Will it still be usable albeit at a lower capacity? What does it mean that the disc is physically erased anyway?

I may try that some other time. I was just hoping someone could speak from experience doing the same thing. Here is a picture of the smudge in question.

That's not a burn mark, but a manufacturing flaw!

By the way, CD's/DVD's burn from the inside out, so just limit yourself to 3 .5 GB and you will miss that mark entirely.

That mark never showed up until I had did that partial erase I mentioned above. I had used the disc before, but never did what I did above. When I erase them I always do the full erase and when done I check the back. Are you saying that I should have been able to do the partial erase and no mark should have been left behind?

Now that I have my external enclosure, it won't be hard to stay below 3.5 GB. I doubt I will even use the discs anymore. I was just curious if I ruined my disc. The external enclosure is just so much easier and faster.

Exactly - the defect didn't show up until it was hit with a small amount of heat. That is why you didn't notice it before. It is a manufacturing flaw. Looks like the thin film is separating from the plastic backing.

A little CD trivia - the top side of a CD is much more vulnerable to irreparable damage than the bottom side that the laser shines through. Most people don't know that. The plastic on the top is much thinner.
