CD/DVD damage?

Post by BAD »

Not sure if this is in the right place or not, but I have some questions about some myths I've heard. Any help would be greatly appreciated, as it will affect how I re-organize my gaming set-up.

1. Is it true that having CDs/DVDs next to your television while it is on can ruin them? More specifically, I stack some of my games next to my TV on both sides; are they or can they be damaged somehow?

2. Is leaving them next to or on speakers damaging? I've heard this a lot, and since I have recently been playing on a mono TV, I am worried about the games I have stacked.

Sorry if this shit sounds stupid, but I don't really know much about this topic; I just know that cleaning disc games with your T-shirt is bad... :D

I know you some of you tech guys can help me with this! Thanks!

No and no.

CDs and DVDs may become warped by excessive heat, so beware of that, but the information on official releases is burned onto the disk, so can only be affected physically.

And a shameless plug for the stuff I'm selling on eBay, if you're into that sort of thing.

Sounds like advice from a time long since passed.

Back in the old days, when we used cassette tapes to hold games, you had to keep them away from magnetic sources. On top of the TV, and next to speakers, were not places to store those.

CDs and DVDs are not affected by magnetic sources.

Cleaning the CD at all by whatever means will leave marks on it. If you use, say tissue paper, the marks you make are simply invisible to the naked eye but anybody with a microscope will still see the scratches. Naturally, a T-shirt is abrasive and will likely leave visible scratches. The game will very likely still work just fine though.

I've cleaned a few cds with a t-shirt, and never had any problem with them (I only do that when I SEE some dirt that makes the game unable to run).

What's the best way to clean a CD? I always wondered that.

There was a myth that cleaning it with toothpast do wonders to it.

If you clean at all, clean inside to outside or vice versa (as opposed to around the disc) so you leave as little consecutive data undamaged as possible.

It's probably best to soak the CD in distilled water and dry it off with a very soft cloth or very soft toilet paper (tissues generally leave too much fluffy residue). In general, you can just wipe dirt off with a very soft cloth but you risk rubbing the dirt against the CD and creating marks. For further visible cleanliness, you may want to consider breathing hot air onto the CD to generate moisture to remove everything off. It's not as clean as distilled water though but you won't notice any scratches as long as the dirt is minute and your cloth/paper is very soft.

I have recommended toothpaste to CDs in the past (and it does seem to work on light scratches) but if you're having problems getting a disc to read, just put it in some boiling water for about 10 seconds. It melts the very bottom layer of scratches, again unnoticeable to the human eye. You CD will seem to magically work better or just fine afterwards. Just make sure to wipe all the water off with very soft tissue (like really soft toilet paper or something) as soon as you can so that the water doesn't leave marks.

IIRC, 100% clothes will not damage the CD's surface.

Your best bet, is to not let the CD's/DVD's get dirty in the first place.
For cleaning though, I fully reccomend those round CD cleaners you can buy in the stereo section of any store.
Yea, those round things where you insert the CD in there...close the lid and spin it around slowly with your hand.
These kits usually come with VERY soft "wipes", with a special high content of alcohol.

Yeah, I usually take really good care of them ever since "the accident." However, I did notice that the cleaning cloth that comes with the PSP has worked well for cleaning my discs...

I've seen that thing about putting a cd in boiling water, but I think I'd never have the courage to do that!

And all the times I used my t-shirt, it was always inside to outside :D

Thanx for all the tips, guys.

Oh. one more questions. Those Lens CD Cleaners that usually have a little brush on the data side, do they really work? Are they worthy?

Boiling water? What madness is that? All it takes is weak glue between the layers (this DOES happen) and you'll have some lovely water moving around inside it, or two seperated halves.

Best way to clean them is a camera lens cleaner kit. They're designed specifically to clean things that must remain 100% scratch free.

Just a note. The data on a CD is actually closer to the label-side, or the top of the CD, therefore scratches on the top are more harmful than scratches on the bottom (clear) side.

Sorry, man, but I've done this over a dozen times with no problems back when I bought a huge set of very cheap used games, some with scratches that made the music or game itself very choppy during movies or gameplay. Although I'll grant that it sounds dangerous and quite unorthodox, it does work.

If you want to test it out (though I don't suggest it considering you'll strain your CD laser, maybe using an old computer), use any useless CD. Use a paperclip and make deep scratches around the CD. Now put it into your computer. It shouldn't recognize the CD at all. Now boil some water, put the CD in there for about 10 seconds, wipe it dry, and dry it again. The CD should work.

Even better, if you have any CD lying about scratched enough that it doesn't even load up on your system, boil it up using the above method and try it again. It should work better, if not perfectly. If the game is really scratched obscenely, well, even boiling won't work. However, a better laser might. If any PS games don't work on your PS1, try them on a PS2 and you'll find that the PS2 laser is far superior at reading.

Anyway, it always pays to test things out rather than claim something doesn't work based on theory. You might be surprised at the results.

Of course, the best course of action is to simply keep your discs in great, clean condition in the first place. But if you end up with a glitching messed up used game from someone else, it's worth a shot.
