All Blank DVD`s will deteriorate with time. The problem is knowing how fast.
I purchased BeAll Blanks about 9 mo ago half +R and Half -R. They all played fine on my Sony standalone and tested ok via transfer rate using CDspeed.
I burrned them using a pioneer AO5.
I chose these DVD
s because they had a 100 year guarantee. How they came up with this I dont know but At the time I would have been happy with 10 years.
Less than a year later none of them play without problems and I
m talking about a lot of DVDs.
The only way to read them is with the pioneer AO6. I cant read them with any other reader or burnner.
The older DVD
s have less stable dye because the process of burnning DVDs is new and they are learning as they go.
MY advice is to buy as you need them and only buy Verbatim TY or Maxell media. The are the only ones that have held up for over one year.
You may have to pay more but your data will be their when you need it.
