    Chris, it's me, mdo7.

    I did some snooping around and according to wikipedia on disc rot. You know how CDs and DVDs used aluminum layer? Yes, aluminum layer within the CDs/DVDs when exposed to air and the environment for a long time could be the cause of disc rot and probably deterioration found in CDs/DVDs. I assume this is the same for the once defunct HD-DVD too (yes, HD-DVD also suffer from disc rot)

    But for blu-ray, they don't used aluminum, they used silver alloy layer. Silver doesn't rust or deteriorate unlike aluminum. So that could explain why blu-ray doesn't faced a lot of disc rot or deterioration like their CDs/DVDs/HD-DVDs counterpoint.

    Now I can't confirmed if this is true about blu-ray using silver instead of aluminum. So Chris, can you find any evidence if blu-ray actually has silver instead of aluminum.
