This is the first I have heard of these “self-destructing” discs. They actually don’t “destruct”, but instead become unreadable. They are known as DVD-D, and come in three different variations. The first is a single play disc, that once played to the end cannot be played again. The second is the 8-hour disc that expires in 8 hours after the seal on the package is broken. And the third is the 48-hour disc that expires in 48 hours after the seal on the package is broken. The DVD-D discs can be played in any standard DVD player.
I am interested to hear more about these, and I wonder how effective this will be.

Seriously? How would they “self-destruct”? Erase themselves.
It would almost have to be triggered by the DVD player’s laser or coming into contact with air. It may be that the data is written to the disc with an organic material that degrades over time once the vacuum seal is broken (much like food).
Cool…
This is a clever idea, but I fear it would produce a lot of waste in the process. I think Downloads are the way to go.
I agree. Even though the discs are recyclable, why waste the resources.
