If you keep your backups long enough, one day man will invent something that will work properly. you might not be alive then but your kids or grand kids will be able to watch your horribly outdated and (by their standards) crude anime.

I dont know where you people think DVDs last only 5 to 10 years. Maybe if you live in a desert and have it sand blasted very day. DVDs are lab tested to last about 100 years. If handle poorly and not kept in the cases sitting in the sun or getting wet will start die within 20 to 30 years. I have CDs from the early 90s that are still working today. I also have one of the first DVDs and that still works today.

100 years?....
actually didn't blue ray advertise something like that when they first came out?

Actually you are right about that. Some of the better quality companies have guaranteed their discs to last 100 years. Most DVD's are pretty much ensured to last 20-30 years minimum anyway. The thing I worry about is that unlike movies that are released, there have been quite a few reports of anime sets being maufactured by low quality producers. Bandai for example had a problem about that with their Gundam Seed Destiny and Code Geass box sets.

Even if you take great care of them. There is nothing you can do about de-lamination or poor quality dvd's If you store it good and leave it in one place sure it could last a long time as long as there is not any moisture. But the more you take it out and play it over and over the durability of it greatly declines.

If you look at this site. near the bottom they have the tests that show some dvd-r only last 1.9 years

From what I read, thats gold discs not silver ones. Silver was about 30 years for well produced ones. But this is all lab conditions, nobody knows how long they'll last in real life properly, as we've not been making them long enough!

Wow, apparently DVD rot isn't real. The only way a dvd can die is either a.) it is well over 30 years old or b.) there is a manufacturing defect or you didn't care for it . Hmmm, that makes me feel a lot better about this.

Manufacturers claim that CD-R and DVD-R discs have a shelf life of 5 to 10 years before recording, but no expiration dates are indicated on CD-R, DVD-R, or DVD+R packaging, nor are there published reports of tests to verify these claims. Still, it would be prudent, in light of these claims, to purchase new discs as they are needed rather than to order large quantities and stockpile them for future use.

Isn't it that when you buy a DVD box set. Those DVD's have a much longer life than ones that you have burned yourself. I believe the "stamping" process that manufacturers use is less likely to cause data loss than burning.

What I posted was time from production until burning. Longer times would create problems with recording the data if I understood it correctly.

I assume that it's for places that aren't moist? So my dry area will keep dvds better than humid areas?

Definitely. Keep them dry, cool and in the dark.

well this is interesting

i have no clue about the lifespan of a dvd but however i when i tried to use the cds i had like years ago it did give errors and jams so i can't see it well enough i wonder if dvds are the same?

however about the market life of dvd i don't think it'll die anytime soon not unless blueray becomes affordable at a reasonable price

The transition between VHS and DVD was a lot different from DVD to BD, since it was really analog to digital, but since DVDs are still a digital format, they're likely to not be phased out as quickly. There's going to be a niche for DVDs for a long time.

VHS wasn't phased out that quickly though. I actually went out to buy a VCR DVD combi just this year as I felt a little lost without my video player!

The transition between VHS to DVD and DVD to BD is still completely different. I was more emphasizing that DVDs are still digital and the media comes in the same physical format, so it's not as dramatic of a switch.

I would tend to disagree though. At least around here, not long after DVDs became the acknowledged modern technology, it was pretty difficult to acquire VHS tapes.

You can still buy a hell of a lot of cheap VHS over here now. Ha ha

One forgets Mr VCD and laser disc. There was a lot of stuff in between before the actual transition.

yeah, but with VCD, people got tired of getting up and changing discs partway through the movie. Laserdiscs were just too big to be stored without being a joke. Not to mention both of them had pretty short lifespans if I could remember.
