Oh noes teh sky is falling!

Both my Sony and Panasonic didn't have HDDs so just recorded straight onto disc. I suppose that was "real time". I did notice, with a recorder disc as opposed to a burnt in a computer that the recorded area had a banded look, not a consistent shade.

I just used Verbatim for DVD and BD Backup, and still play fine. I have several hundred Backups, and they should all still play. I stopped burning around 2015, and started to build my Digital Collection. The last one I recall playing was Surrogates a couple of years ago, it played good. I watch all my Movies and TV Shows Streaming now.

I don't think Sony make any blu-ray recorders with a built-in hard drive any more - I mean the ones which allow you to dub over onto a disc like my old machine could do. The only recorder I'm aware of that comes closest to having this is a Panasonic model - DMR-BWT850, which I recently saw at my local AV shop. I didn't really look at all the details, but it certainly was a nice looking machine.

I only have a few 25Gb BD-R's, but I use to buy them on eBay from Japan. When I started burning I did try other media, but found Verbatim to be the most consistent in good burns so I stuck with them.

Yes, that's fair enough. I don't have any BD-R's at the moment that I've burnt myself, but as I never had any problems with Verbatim in regards to their DVD-R's (either burning or playback), I would certainly be happy to use them for blu-rays too.

My finding with pressed disc media over the years is that they either go bad within 2 or 3 years, or they never go bad (not counting mistreatment or storing in a moldy basement) I've lost a few Laserdiscs due to laser-rot and it was always within a year or two of buying it. Last time I went through my pile of LDs, not a single one of them that was fine 20 years ago had developed any problems since. Same thing with a lot of the dual layered dvds, they either stopped working in a couple of years or are still fine to this day. Granted I haven't rewatched every single disc to know for 100% certain but I have never had a problem with any CD, LD, DVD or BluRay that was fine after around 3 years.

Blu ray discs are pretty hearty. You almost have to go out of your way to damage them. They also last a very long time in the right conditions. I’ve seen defective discs and picky players though..

[stonesfan129]

They do degrade but it takes a very long time. Commercial discs pretty much last forever if made right and taken care of. Burned discs (I think the LTH type, can't remember) that have the dye will degrade faster. I have yet to have a Blu-ray disc go bad. I have had a couple that were defective out of the box that I had exchanged.

[mdo7]

As everyone on this thread said, I think you got a case of a defective discs (that's the problem with the early days of BD). So just follow direction on how to get it replaced.

Also BD don't seem to have disc rot problem, although one article from last year talked about disc rot, and this got my attention:

Is Blu-ray Safe from Disc Rot?

It seems less prevalent than for CD, DVD and LaserDisc, but it would be unwise to rule out Blu-ray disc rot. There are a few reports of disc rot on Blu-ray which has been described as ‘small mould blooms’ below the surface, rendering the disc unplayable.

So please keep an eye out on your BD in your collection if you see any sign of disc rot or degradation.

Vice News in 2017 had an article about disc rot and why it's a big concern for archivists. Blu-ray is not talked about in the article, but there's a reason why a lot of movies that got DVD release, but no 2K/4K scan restoration blu-ray release is a big concern for DVD owners. Your movie in your DVD collection, keep checking them periodically from time to time to see if they don't show sign of disc rot/degradation.

So far as of now, it doesn't look like BD have any major disc rot problem. But keep checking your BD disc in your collection to make sure from time to time to make sure the disc doesn't show any sign of disc rot.

I've had a bunch of DVDs go bad in my collection. Oddly enough, all the ones that went bad were DVDs I bought later on during the format's life, most of which were Fox DVDs. The ones I bought as early as the year 2000 never went bad. And this leads me to believe that later on, DVDs were manufactured more cheaply and thus, making them more susceptible to degradation.

I've never had any of my BDs go bad on me though. So, knock on wood...

[chriscreep23]

I have read an alarming article from the Canadian Conservation institute that estimates the life-span of read-only, pressed blu-rays. Although most of the article is about DVD-Rs etc at the bottom of the article there is a small section about read-only blu-rays and a chart that estimates the life-span of them up to 10-20 years. Is that true?

If anyone wants read some take you should read this recent “study”
That claims the upper limit of blu ray disc life Span is 10-20 years for a pressed disc

https://www.filmstories.co.uk/featur...blu-rays-last/

[johndoyle123]

A recent Canadian “study” has shown they believe the top end life span of a pressed blu ray disc to be 10-20 years. Despite us having numerous manufacturer stress tests and private aging study’s showing it being more likely 50-150+

Where do you stand on this ? How long do you think your discs last

I’m thinking at this point they have a good chance of outlasting me.

Seriously, if you think about it that's all they need to do

[Ricky G]

Depends on how you treat them and store them. Don't let your kids use them as Frisbees or leave the discs out on your coffee table like they're coasters and they'll be around forever ever.

Way to many variables to predict a given life span. I have some CD's from 1983 (37 years old) and they still play just fine.

Burned disc life span is another subject.

[CSM101]

Most of my discs are just fine. I have a bunch of burned music discs that are over 20 years old and no issues. I have a few blurays that just stopped working. Hellboy 2, Enter The Dragon (first issue) , and most recently, Saw. I even have a few bronzed up discs that are still working. I personally think most of my discs will probably outlast me.

[jkoffman]

The Canadian study shared here details recordable discs, not pressed. There's absolutely no info about the 10-20 year lifespan they suggest. And the FilmStories author's "study": "It took me only 13 discs to find one that would no longer work at all, and 11 more to find another." Come on.

I was a teen in the 80s and just the right age to be an early adopter of CDs. I've worked in music stores, had my own online media resale business starting with ebay in 1998, and worked in the music business for 30 years now. In all that time of handling at least 10,000 CDs, I could count on one hand the CDs I've seen that have literal rot, and usually of known titles from the 80s. Of my own CDs -- at its height, I had about 3000 -- and 2000 DVDs and BDs, I've never had a single one deteriorate or become defective. Do I think they'll last "forever"? Of course not, but carefully stored and only removed when playing is the bar we should be judging by.

I have many DVDs that I purchased in the 1990's that are as good today as they were when I purchased them. Given that, if you use and store your Blu-rays properly they'll last a very long time.
