well I hope not since I have 10 of them stacked on top of each other, since I ran out of room on my shelves.

only if all 10 are snappers.

My dvd drive is mounted vertically (its a PS2)

Hey folks, no need to be such schmucks... The original poster deserves more respect than this--it was a fair question. I've read in some places that it is bad to store DVDs horizontally--I don't believe that's true, mind you, but filling the thread full of jokes and a few attacks on the OP just isn't called for.

i hope people realize i was being sarcastic with my comment.

"Correct me if I'm wrong, but if storing them horizontally can cause damage, shouldn't we have vertically mounted DVD drives?"

Not if they're not left in there long term.

I was reading somewhere about how even though many people think dvds are sturdy they are actually not, and while people think that's important for the bottoms to be protected, you know from scratches and such, dvds are actually very suseptible from being harmed through the top. I guess the top is very thin, and setting stuff, even light stuff on top of a dvd (why you'd do this I don't know) is a very bad idea.

Aughh!! I've had a bunch of DVDs sitting horizontaly-- some for over years-- and wouldn't you know it. I pop in my Family Guy and Disc 4 won't work. I look at the disc and it's got all there blots streaking out from the middle! Damn!

Then I just happened to open some of the old WB snappers and there's a warning there to only store them vertically. Damn!

Screw this, from now on it's originals in storage and DVDXcopies on the shelf.

I wonder what Austin the librarian would say, he's got his enormous DVD collection in piles stacked horizontally, based on the pics he posted

Anyway, storing optical discs vertically would discourage the possibility of the perfect flatness of the discs to sag or warp due to gravity, I think.

Horizontal storage is bad for LPs and laserdiscs. Warpage was a serious issue due to their size and the limited protection offered by their cardboard sleeves.

DVDs are much smaller, and keepcases distribute the weight placed on top of them away from the discs. Warpage is not a legitimate concern. In over two decades of CD ownership, I have never once heard anyone complain of their CDs warping because they were stored horizontally.

I think you mean horizontal, not vertical.

Kimiakane, you know that we all love you here (especially those of us who have checked out your homepage!). Please forgive us for having a few laughs in your thread.

That said, I have decided that most of my damaged discs have incurred that damage in the process of putting them into and taking them out of the player. Therefor I am simply going to buy a player for each disc that I have so that they no longer have to be removed!

D'oh! Thanks. Edited now.

If anyone is truly concerned this is supposed to be the definitive info on this topic

Thanks for the guide

Quoted from the guide...

5.2.6 Flexing
Flexing (bending) the disc by any means, such as removing it from
a jewel case or sitting on it, may harm the disc by causing stresses. The disc should be stored in its case and placed vertically, like a book, on a shelf. Long-term horizontal storage, particularly in a heated environment, can cause the disc to become permanently bowed. While the data may still be intact, the disc may not operate properly in the drive or permit the laser to follow the track. The maximum degree of fl ex (bend) or number of times a disc can be fl exed before it incurs damage is not known. To minimize the risk of damage, it is better to avoid fl exing discs.

Interesting point below... is it the reason Universal has stopped putting inserts in the keepcases?

5.1.6 Individual Disc Storage
For long-term disc storage, it may sometimes be prudent to remove the label insert or booklet from inside the case and attach it to the outside, perhaps in a sleeve. In theory, the paper can attract moisture and produce higher moisture content in the case. The paper may also spread moisture by contact with the disc. This recommendation is based on no specific tests of the effects of paper inside a case; it is merely a consideration—one that takes on added significance with large amounts of paper inside a disc case and higher-than-recommended humidity conditions.

Now I am paranoid about my discs being stored horizontally. I bought 3 dvd disck racks, were the discs slide in horizontally. If this is bad why did the company make the dvd rack that way? I feel like I have wasted money on my hands now.

emhello

Yep I'm screwed.

Since the dye is essentially liquid, wouldn't it make more sense to store them horizontally?? Makes more sense to me that gravity (over a long period of time) would cause more problems if stored vertically.

Dye? Prerecorded DVDs are pressed and do not use dye. Recordable DVDs are a different story though.

emhello

Yeah I was thinking more of the DVDs and CDs used for backing up data.

Qui Gon Jim

you forgot the quotes on "backing up"
