Visual Defects in DVD Surface

I'm petty sure I've seen some info on this before, but I cant find it. I've had a few failed burns tonight. When I looked at the discs, I noticed what looked like some defects disc near the outer edges. I'm not sure what defects look like though. I can see what look like smudges that start at the edge and go toward the center of the discs. Could someone please tell me what I should be looking for or maybe post some scans of bad discs. I only have a digital camera and it's impossible to take a picture of what I see. Thanks!

Well, I got out the tripod and got this pic. Is this a defect?
