Has anyone had any problems with DVDs warping on a shelf over 5 years or so? Supposedly after a period of time a DVD can warp from only resting on the DVD case's hub. According to a friend of mine this is one of those things he's never seen in real life but supposedly happens. I'm wondering how to prevent it, besides putting my discs in a DVD binder, if there is a way. I'm thinking one could stack their DVD cases/sets horizontally thus producing less pressure between the inner ring of the disc and the hub but I'm not sure if it would actually work. I'd like my collection to survive for more than five years, please contribute if you can.

Never heard of that before. I've been buying most of my DVD's in binder's, this however was mainly for me to easily get DVD's after I had my second surgery since I didn't want to walk up and down stairs to my basement and have to bend over and pick up plastic storage contains which hold DVD's cases. I still have a few that I need to put in DVD selves but I don't have enough space for all of them since I have a buku amount of DVD's that I own (Mostly the DVD's that I have are non-anime.) I liked the idea of the sleeve since I would have to move things around a lot of to get to what I want to watch.

If anything, putting your DVDs in a binder could potentially be even worse to warping than storing them in separate cases, if you store the binder lying flat, and if you have an uneven number of DVDs distributed within its pages.

I doubt DVDs would ever warp if you store them in their original cases no matter how you position them. However, if you worry about this, simply store the cases vertically (like they are often found on store shelves). There is absolutely no way the discs would ever warp in such a position. There is only the potential for warping if you store the cases lying flat, stacked on each other.

Even if your DVDs did warp that would not be the end of the world. Simply take your DVD out of the case and put it in facing the other way, then wait another 5 years and they will warp back to the way they used to be.

I'm personally a lot more worried about my laserdiscs warping than my DVDs, since I tend to stack mine flat from the ground (much like you would find in a binder) and they have no protective hard casings like DVDs do, and they are way bulkier and more bendable.

I've got DVD's that have been on a shelf for well over 5 years and never had this problem, maybe it depends on the room temperature and the conditions they are kept in.

Does the person your friend heard this from live on the sun?

I agree with kill that maybe the condition those cd's were stored were not the recommended.

I've had Dvd's warped that I've left by a table by my window and someone decides to open my curtains and the sun eventually takes its toll. But even inside its cases I've never had an issue.

I once left a DVD case on mycars passengers seat for 2 hot California days in a row, the sun was hitting it too cause when i picked it up the case was HOT, but the DVDs inside still work to this day, Area 88 OAV (clear case too)

As long as you're being somewhat careful in the care/storage of your discs (put it in a case, keep out of direct sunlight, etc.) I don't see any real issues.

Threads like this always encourage me to watch Earthian, since it was my first anime DVD and I can pinpoint its age pretty well (purchased June 2001). Haven't had a playback issue yet! Wink

I have a few DVDs that date back to 1998 and have not noticed any warping on them. I assume that the issue would apply to CDs as well of which I have a good number that are over 20 years old that show no signs of warping. Sounds like a myth to me.

I'm always paranoid of laser rot on LDs. I actually watched my Gundam films on LD a few days ago to listen to the original mono audio mix and forgot how loud these machines were.

I think storage is a big thin on determine if something will last a long time. I keep most of my DVD's in attache case like binders which are out of direct sunlight in my room which for the most part is fairly cool and never really hot.

For the DVD's that I still have yet to put in binders since I don't have enough room, are kept in my basement which is cool all year around. I usually just end up putting the DVD cases on my book shelf or put them in plastic storage containers to save space.

I don't think any of my LDs have laser rot so far, none of them have any blemishes that I can see other than possibly a few surface scratches. However a number of my LDs no longer play very well (there will be occasional glitching of the video during playback) even though the discs still appear to be in pristine condition. For example my AnimEigo Oh My Goddess! discs have this problem. Some of my import Japanese LDs have this problem too such as Magic Knight Rayearth.

Yet most of my LDs still play perfectly or near-perfectly (maybe with one or two frames containing a tiny one-pixel glitch during playback of the whole disc, which a normal person would not notice). Although I am not sure because I don't own a huge collection of laserdiscs, it appears that the development of this problem is series-related. Because OMG Vol. 1 developed this problem then so did OMG Vol. 2. But if Ruin Explorers Vol. 1 didn't then neither did any of the rest. I don't think storage conditions is the explanation because most of my LDs have been stored in the exact same place and way.

Or perhaps my discs were always that way (some manufactured more perfectly than others from the start) but my LD player(s) laser got slightly worse over the years so the effect on playback became more visible.

Even my discs that don't play well are still pretty good and are excellent to watch. But I've been transferring some of my LDs to DVD with a DVD-Recorder to help ensure their preservation forever (in case my LDs rot away) and when I do that I become super picky about even the tiniest glitches because I'm making a digital copy that I hope to last forever.
