More Bad News on DVD Rot
« on: Jan 21, 2004 at 05:49 PM »
"If you think your prized collection of DVD movies will last a lifetime, think again - some are already starting to rot while others are falling apart.

"Unofficial estimates put the number of affected discs at between one and 10 per cent. Yet some of the largest distributors for Hollywood Studios are accused of refusing to accept the problem exists and replace faulty products."

this is old news. we have to distinguish between unstable batches and natural deterioration. dvds from unstable batches will exhibit dvd rot or delamination almost immediately. on the otherhand, i've yet to have a dvd that's been with me for a while go suddenly unplayable except if its from a suspect batch like Superman special edition or Dr. Zhivago.

Makes me wonder if DVDs are worth collecting if they will rot after some time.  Siguro it's wiser to dispose of then after playing enjoying them once..  Afterall, once the HD-DVD comes along, here goes another buying spree upgrade for the titles i like.   All these DVDs will be obsolete and not compelling to watch anymore.  So totoo lang, i think 99% of my DVDs just stay on the shelf after watching once.

If disks are defective, then why aren't manufacturers admitting that there's no problem? If disks will deteriorate naturally, how long will they last? And if a new format appears, which might make the present format obsolete, does this mean that I will have to buy titles all over again?

Do we need to focus on the manufactured DVD's itself?

How about climate factors? Case? Cabinets? Package?

i store mine in a suitcase, where there no dust and its at a fair temperature room.. no aircon, since i heard this causes moist and lead to faster deterioration due to changes of temperature

From Yahoo News:

CDs and DVDs Not So Immortal After All
Wed May 5, 1:59 PM ET  Add Technology - AP to My Yahoo!
By PETER SVENSSON, AP Technology Writer

Dan Koster was unpacking some of his more than 2,000 CDs after a move when he noticed something strange. Some of the discs, which he always took good care of, wouldn't play properly.

Koster, a Web and graphic designer for Queens University of Charlotte, N.C., took one that was skipping pretty badly and held it up to the light.

"I was kind of shocked to see a constellation of pinpricks, little points where the light was coming through the aluminum layer," he says.

His collection was suffering from "CD rot," a gradual deterioration of the data-carrying layer. It's not known for sure how common the blight is, but it's just one of a number of reasons that optical discs, including DVDs, may be a lot less long-lived than first thought.

"We were all told that CDs were well-nigh indestructible when they were introduced in the mid '80s," Koster says. "Companies used that in part to justify the higher price of CDs as well."

He went through his collection and found that 15 percent to 20 percent of the discs, most of which were produced in the '80s, were "rotted" to some extent.

The rotting can be due to poor manufacturing, according to Jerry Hartke, who runs Media Sciences Inc., a Marlborough, Mass., laboratory that tests CDs.

The aluminum layer that reflects the light of the player's laser is separated from the CD label by a thin layer of lacquer. If the manufacturer applied the lacquer improperly, air can penetrate to oxidize the aluminum, eating it up much like iron rusts in air.

But in Hartke's view, it's more common that discs are rendered unreadable by poor handling by the owner.

"If people treat these discs rather harshly, or stack them, or allow them to rub against each other, this very fragile protective layer can be disturbed, allowing the atmosphere to interact with that aluminum," he says.

Part of the problem is that most people believe that it's the clear underside of the CD that is fragile, when in fact it's the side with the label. Scratches on the underside have to be fairly deep to cause skipping, while scratches on the top can easily penetrate to the aluminum layer. Even the pressure of a pen on the label side can dent the aluminum, rendering the CD unreadable.

Koster has taken to copying his CDs on his computer to extend the life of the recordings. Unfortunately, it's not easy to figure out how long those recordable CDs will work.

Fred Byers, an information technology specialist at the National Institute of Standards and Technology, has looked at writeable CDs on behalf of government agencies, including the Library of Congress (news - web sites), that need to know how long their discs will last.

Manufacturers cite lifespans up to 100 years, but without a standardized test, it's very hard to evaluate their claims, Byers says. The worst part is that manufacturers frequently change the materials and manufacturing methods without notifying users.

"When you go to a store and buy a DVD-R, and this goes for CD-R as well, you really don't know what you're getting," he says. "If you buy a particular brand of disc, and then get the same disc and brand six months later, it can be very different."

This renders the frequently heard advice to buy name-brand discs for maximum longevity fairly moot, he says.

DVDs are a bit tougher than CDs in the sense that the data layer (or layers — some discs have two) is sandwiched in the middle of the disc between two layers of plastic. But this structure causes problems of its own, especially in early DVDs. The glue that holds the layers together can lose its grip, making the disc unreadable at least in parts.

Users that bend a DVD to remove it from a hard-gripping case are practically begging for this problem, because flexing the disc puts strain on the glue.

Rewriteable CDs and DVDs, as opposed to write-once discs, should not be used for long-term storage because they contain a heat-sensitive layer that decays much faster than the metal layers of other discs.

For maximum longevity, discs should be stored vertically and only be handled by the edges. Don't stick labels on them, and in the case of write-once CDs, don't write on them with anything but soft water-based or alcohol-based markers.

Also, like wine, discs should be stored in a cool, dry place. Koster's friend Mark Irons, of Corvallis, Ore., stored his CD collection in a cabin heated by a wood-burning stove. The temperature would range between 40 degrees and 70 degrees in the space of a few hours. Now, the data layer of some of his CDs looks as if it's being eaten from the outside.

Irons is still pretty happy with CD technology, since it beats vinyl LPs and tape for longevity. Now that he's moved his discs to an apartment with a more stable temperature, he's noticed that the decay has slowed.

"I'm hoping they'll hold out till that next medium gets popular, and everyone gets to buy everything over again," he says.

DIY shops have them but I don't know if all.  Meron sa Handyman (Robinson's Place) they gave me a brochure with the price list but lost it though.  Check to the nearest DIY shops near you sir. HTH  :)

After reading the article on CNN, I checked some of my older audio CD's bought in the late 80s and found that some DID have signs of rot. Will our DVDs soon suffer the same fate? Does anyone know if there has been steps undertaken by DVD manufacturers and the studios to prevent this from happening?  :'( I only know that some make your discs eligible for some sort of replacement program when you register them online. What about the others?

Our Monster Inc. Disc 1 suddenly stopped playing, whereas it used to play flawlessly, and this was one of our most watched DVDs before this happened. Despite repeated viewing, there were no scratch or marks on the disc, it was perfect. DVD and case still as nice as when we first had it. Cleaned our player, did all those stuff one does when skipping/pixelating happens...nothing. Cleaned the disc just to be sure....nothing.

Wrote Disney and supplied them with the numbers found on the disc, as they would usually require. Pagkahaba haba pa ng explanation ko on what I've experienced. But after a couple of weeks, I got a useless reply saying I should check my player..?? One suggestion from that email even said - Is the DVD player on?  Hello!

Went to a US DVD Forum and found out I'm not alone. Some of them had their copies replaced immediately from where they bought it, covered pa ng replacement window (or whatever you call it). But I discovered ours isn't working anymore after over a year and a half (bought it in Sept 2002)....so, what's the use, eh? Well, on the bright side buti na lang napanood ng sobra sobra bago nag-rot. :)

This is so scary naman.  You mean to say after taking good care of our dvds and spending so much for them ... they will rot lang din after a while.

Makes one think if this collecting of dvds is all worth it.  We are so passionate about this pa naman tapos dvd rot lang din pala ang bagsak  :'(

Aren't studios obliged to replace your discs specially if the rot comes prematurely? Or di lahat may disc replacement program? Which studios have one, btw?

i remember reading somewhere in the forum or some other webisite about caring for dvds, and they mentioned that we should avoid storing the dvds in jewel cases because when the dvd spins while in the case, scratches may occur...
so does that mean our dvds of LOTR EE series should not be where they are originally in? btw, i noticed a very itsy bitsy teeny weeny scratch on my disc 4 after opening it.. it was fresh sealed after i discovered the tiny scratch!  >:(

When i read that article, it says that there are factors which contribute to cd or dvd rot. one factor was that the owner used to store his cds or dvds near a very hot place. But as anybody who bought the Superman SE R3 would know, some batches of dvds are unstable and would deteriorate after a certain period of time.

I hate these sort of news ... makes me wonder why I buy them in the first place (at a price that's quite painful to the wallet).  :'(

I also had the assumption that the DVDs would last at least within my lifetime (which I hope is a long one!!).  That is why I decided to buy the DVD format rather than the VCD format.

Lets just hope Ms. Cruzack is right in saying that its just a 1 to 10,000 chance and that the DVDs do last a lifetime.

As for the info that flexing/bending the disc might cause damage to the discs, hirap minsan at there are a few that you literally have to "bend" in order to get them out of their cases!!

Are there any updates regarding the cause of DVD/CD rot, and how we can prevent it happening to our respective collections
