How long will our Blu-ray Discs last ?

[HorrorBlu]

There's a thread on here where people report when their discs have gone bad. For the most part, most of the blu-ray issues are isolated to LionsGate and Fox releases circa 2006-2012. As for DVDs, Warner's dual-layered discs are the most likely to go bad over time.

Of course, there are always exceptions, but outside of these companies, most seem pretty reliable.

Do any of you guys know how many Disc Factories are left? I don't think each Studio has their own. I heard in North America there were two left. Of course each Studio has to make their own Digital Master for a particular Disc.

I'm not worried. I've got CDs that are 35+ years old that still play fine. Take care of them and they will last.

Studios never had their own factories.

I've got some Disco Vision discs from 1978 that still play, a little disc rot sparkling but can still view them. That's about 42 years.

The worst I've seen are WB HD DVD's. I've got a stack of those I need to recycle that went bad. Some went bad early. Some went bad between 2017 and 2020.

I should hope to last as long as my discs will.

Here's is an interesting article. What do you guys think of it?

As of now, I haven't seen any article or evidence of mass BD deterioration or a mass disc rot involving BD.

Does anybody know when Sony (and to greater extent, Blu-ray Disc Association) planned and developed blu-ray before it became a mainstream format standard, did they ever had plans for preventing/combatting disc rot and deterioration? I want to know because if blu-ray disc come with measure to combat disc rot and deterioration, then that disc standard is way better CDs and DVDs when it comes to disc rot and deterioration.

I think you need to chill out

Since this I’ve read many other studies online which I paid for, I have had emails with data archivists and spoken with others i the know (who worked for Panasonic) and there is no evidence of any wide spread disc rot, aside from known production issues that have caused bad batches.

There are also no realistically circumstances to put discs through any form of stress test like real world tests.

Replicated media is designed to last up to 100 years + was the basic concluding

Well there's another reason blu-ray won't really rot. DVD use aluminum reflective layer, right. Aluminum rust and decompose over time, am I correct?

Blu-ray doesn't use aluminum, they used silver alloy over aluminum. So using silver over aluminum for blu-ray is probably the reason why disc rot isn't common on blu-ray.

But silver oxidizes too.

That guy however did not put his DVDs under extreme environmental conditions but they degraded nonetheless

I did some research and yeah you're correct. But it looks like it doesn't cause a serious problem for BD (then again, some stories of disc rot or BD not playing back on players varies differently). So I can't jump to any conclusion for now. Need more research and evidence to make a good conclusion about BD disc rot.
