I am having a problem with my burned cd's and dvd's going bad. They work fine after I burn them, but within a year or two I start having trouble playing them/pulling data off of them. When I examine the disks, they don't have any scratches on them, but they don't look right either. Some look discolored in parts, some of the cd's actually look like the aluminum inside the cd started to peel back. These disks did not have any labels on them, were stored at room temperature, out of direct sunlight. Pressed disks(store bought originals) stored in the same area do not have these problems. These disks were generic. I have since switched to buying Taiyo Yuden brand blanks. I am wondering if a year or two down the road I will have the same problems with my Taiyo Yuden burns. What's the oldest TY burn someone still has? When I see the TY name, can I assume all their disks will have the same longevity or only the ones that use dye 123 from lot 456 and plant 789?
