weird mark on dvd disc

[bogo5]

Just curious what this mark/line is? the area of the mark is a slightly different colour. The dvd is 6yrs old & plays fine. Just wondering if its a sign of deterioration.

Looks like the disc is decaying a bit, not sure how much longer you have before it stops playing.

Does it occur by it self? Thought dvd's were meant to last alot longer when just sitting in the case.

Actually it may not be disc rot, it may just be natural warping. DVDs are actually notorious for going bad though, a problem they've almost rectified with blu-ray.

good to hear. I still try to keep my old dvds stored away in a safe just in case something bad happens to my BD collection. dvds still better than nothing.

A few of my DVD's have that mark. It hasn't affected them....yet

IMHO, it's neither warping nor deterioration. It's the glue keeping together the various layers of plastic that a disc consists of. I have this on discs older than 10 years, and doing a disc quality scan of them in a DVD-ROM, they appear without any significant error rates. Goes without saying they also play back fine, of course.

I would be inclined to agree. I've seen this type of marking on brand new dvd releases that I've either purchased or rented over the last few years and have not noticed any issues (i.e. playback, etc.). One thing of interest though, would be if you remember looking at this disc 6+ years ago and not noticing this mark being there. With what I've seen, chances are it may have been there when you first got it.
