DVD disc Fungus?

[gamemaniaco]

1 DVD + R creates and catch fungus?

2 my DVD + R before handling Always wash hands with water but unintentionally I touched down on the surface of the disc, I'm worried about fungal growth on the DVDs?

[jman98]

Since this whole thread is idiocy, you're going to get my grammar lecture. Sucks to be you.

Putting a question mark at the end of whatever the hell you feel like does not make it into a question. It DOES make YOU into an idiot though.


I've never heard of fungus being able to grow on the surface of burnable media just because someone touched it. The hard transparent layer should not allow such growth, if it even is possible, to penetrate to the lower layers.

[Kerry56]

Are you saying that you have a disc with fungus on it, or are you simply worried that it might happen?

Fungus has been known to get inside the disc in extremely hot and humid climates, but even there it is rare. And since discs are normally sealed, it is more likely to occur with poorly made discs.

External fungus shouldn't be an issue, as you can clean the exterior surfaces. Fingerprints can leave a bit of oily residue, and get dirt stuck on as well, but again, this is a minor problem and can be cleaned off with a little bit of alcohol/water mixture.

[gamemaniaco]

I do not have a disc with fungi but I'm worried that this may occur


DVD + R can create as mold fungi?


I touch the dvd disc on both sides and I'm afraid of leaving any residue that attracts fungi and can destroy my media and my data but I do not want to clean using anything in the media not to scratch or damage


before touching the disk I washed my hands

[Kerry56]

Fungus on the surface is not a problem I've heard of. So you shouldn't worry about this.

If you use a clean, soft cloth with some alcohol/water mixture, you can clean the surface of your dvds. You won't create scratches that will affect playback.

[gamemaniaco]

1 is proven that medias DVD + R has no risk of creating mold, mildew and fungus?


2 You said DVD + R not create fungus which destroy the medias and data which are those spots and points that appear in some medias and then increase in size?


3 What are all the signs of degradation medias DVD + R?


4 do not intend to spend any cloth with any product not to run the risk of damaging the media, if you have any fingerprint'll leave but I'm worried that creates fungus

[Kerry56]

#1...not proved, no. But the disc is made of two pieces of polycarbonate glued together with a reflective coating and a dye layer inside. The polycarbonate is basically a neutral substance that does not generate or provide an environment that would cause mold, mildew or fungus to grow. You would need to add a foreign substance on top of the polycarbonate, plus water/humidity. Oil from fingerprints is not enough to cause this.

#2 Spots sometimes show up on burnable dvds because of poor dye dispersion, poor burns, inferior dye composition, excessive heat and/or ultraviolet light. The solution is to buy the best quality discs available (generally Verbatim, Taiyo Yuden and FTI Falcon) and store them in a cool, dry, dark area.

#3 Degradation of media applies to both -R and +R. Poor playback is a first clue, though you may have suffered a poor burn to begin with. Dyes used in these two formats are organically based, and will deteriorate over time. That is a fact. Whether that time period is a year, a decade, or five decades, the deterioration will occur.

#4 You "do not intend" to use a cloth and cleaning solution. This is your loss and is utterly stupid/short sighted/ignorant...take your pick. Have fun reading data through fingerprints.

Thanks for the reply, I hope you continue helping me


1 First the top layer (media name) and lower layer (glossy layer) of the disc is made of polycarbonate?


2 is proven that polycarbonate does not create and do not develop mold, mildew and fungus?


3 My disc dvd was not wet, it just took fingerprints from my fingers and I am in doubt whether these impressions have oil and organic substances that create fungus and can destroy the media


4 I did not buy the best discs because I did not find to sell, so I bought philips dvd + r cmc mag m01-00 and cmc says he uses AZO dye system but in about two years I intend to buy my current best if these are ok there


5 what are those disks with spots and stains that appear in them? are fungus? which signs of degradation?

[jman98]

I see he's back to the old "The questions never stop" game he began here:https://forum.videohelp.com/threads/358471-Questions-quality-Philips-DVD-R-CMC-MAG-M01?...51#post2265051


Note in his post #9 (and in my link) that he believes CMC when they tell him that they use AZO dye. HA HA HA HA HA HA HA... Wonder how much he would pay for me to sell him the Brooklyn Bridge?


OK, I'm going to let genemaniaco know the secret that we've all been keeping from him. Yes, touching the disc will cause fungus to destroy your disc eventually. You can kill the micro-organisms by putting the DVD that you touched in a microwave oven with the burned side up (not the label side). Turn on the microwave over for about 10 seconds. I guarantee you that no micro-organisms will survive.

Not all Brazilians are Internet trolls, of course, BUT the Brazilian trolls usually are "better" (read: worse) than the trolls from other countries.

I live in Brazil and I do know what I am talking about

1 First the top layer (media name) and lower layer (glossy layer) of the disc is made of polycarbonate?

The disc is made of two pieces of polycarbonate. They are glued together and in between them lies the dye layer and metallic reflective layer. The company that sells the discs often times applies a sprayed on coating on top of the disc where they put their brand name and information about the disc.

2 is proven that polycarbonate does not create and do not develop mold, mildew and fungus?

No, I have no studies showing that polycarbonate is magically immune to mold, mildew and fungus. These things can grow on any surface given the right environmental setting. But the polycarbonate and applied coating on the top of the dvds will not, in themselves, be conducive for the growth of these types of organisms.

3 My disc dvd was not wet, it just took fingerprints from my fingers and I am in doubt whether these impressions have oil and organic substances that create fungus and can destroy the media

Even if fungus did grow on the outside of the disc it can be easily removed without damaging the disc. Its not like the fungus will etch the tough polycarbonate surface.

4 I did not buy the best discs because I did not find to sell, so I bought philips dvd + r cmc mag m01-00 and cmc says he uses AZO dye system but in about two years I intend to buy my current best if these are ok there

I don't recommend CMC Mag M01 discs in general. If they are the best you can get, then use them, but their performance will vary depending on too many factors to list. Your drive will have to match up well to them in its firmware.

5 what are those disks with spots and stains that appear in them? are fungus? which signs of degradation?

I'm not sure which ones you are referring to, but poor quality discs will sometimes have spots in them. They usually don't burn well. I listed some reasons earlier. Fungus inside the disc is very rare. I've seen examples of it, but have never had one personally.

And that really should be the end of this discussion. Asking the same questions over again will not give you different results. But then Einstein said it much better than I ever will.

1 I saw one on a website that there is a fungus that eats the DVD Polycarbonate his name is Geotrichum


2 What does create fungi is only water and moisture? for here I think has no such problems in medias


3 dvd discs have here with several years and in the center it in the hole has finger marks but has no sign of fungus, only I played the disc faces but not wet and not sure if this fungus produces

[hech54]

3 dvd discs have here with several years and in the center it in the hole has finger marks but has no sign of fungus, only I played the disc faces but not wet and not sure if this fungus produces

That's because, as you have already been told countless times, the "mold"(more commonly referred to as Disc Rot on idiotic web sites/pages) IS NOT CAUSED BY FINGERPRINTS.

[gamemaniaco]

1 The material used in the center of the DVD (transparent plastic) is different from the material of the two faces of the disk where the data are recorded, has the brand name and is shiny? I have some dvds a few years here and saved in the center of the disc has fingerprints but no signs of fungus, but as I played in other parts of the disc was wondering if the material is the same as the center of the disc and produces no fungus


2 you said mold "(more commonly referred to as Disc Rot on websites / webpages idiot) are not caused by fingerprints, then what causes Disc Rot?


3 The DVD + R from any manufacturer has some layer or protection against scratches common on the face down (shiny) disc dvd? my disc has minor scratches


4 you need to have the disc to create fungus?


5 which are the persons responsible for the data layers and by reading the disc? they are protected by some layer?


6 is true that all companies apply a spray in superficie the DVD? so he serves? they also apply the spray in the face down (shine)?

Someone ban him from ever having internet access again!!!

[johns0]

This thread has officially gone moldy,hmm,my beer glass has fungus on it.

[poisondeathray]

So what can I do about this ?




(Are these edible ? )

[deadmeow]

Nothing lasts forever. But look at it this way. We have CDR, DVDR and BDR. You can back up large amounts of CDR's onto BDR's. When we get to the next era of writable discs after BDR's, you can slap a large amount of DVDR's onto that, and so on. Not to mention the low prices of hard drives.

[vkmast]

The disc may or may not last, but definitely a problem with the player there.

[usually_quiet]

I think the OP probably read something like this http://www.myetymology.com/encyclopedia/Geotrichum.html

I suppose there may be bacteria and other microorganisms capable of feeding on adhesives, organic dyes, and some other materials used to make DVDS, but that almost never happens even in a hot, humid, tropical environment. Otherwise we would hear a lot more about it.

[gamemaniaco]

1 Only by contact of the fingers with two faces Disc DVD + R creates the possibility of generating fungus medias? Always wash your hands before handling the medias but do not know if that puts contact materials that generate fungi


2 My DVDs were not wet and not in humid environment, moisture is responsible for creating fungi? no moisture has fungus?


3 Disc DVD + R from any manufacturer or protective layer that prevents any data or byte is lost or damaged the disk is read in case of scratching the shiny layer down?

1. You do not need to wash your hands before handling DVDs unless your hands are dirty, sticky, or greasy.

2. Yes. Molds and fungi need moisture to grow well.

3. http://www.digitalfaq.com/forum/media/1422-discs-scratch-resistant.html#post8465

[gamemaniaco]

1 apparently my hands were not greasy, even so I washed my hands with soap before handling medias


2 I even touched the fingers and dvd discs left fingerprints, if not the humidity there is no danger of creating fungi in the media?


3 box slim of medias DVD + R discs protects from moisture or not? the boxes of my DVD + R equals the boxes of CD, the DVD boxes slim protect?

[turk690]

The OP may or may not have anti-fungal obsessive-compulsive disorder or is conflating it all with 80s laser-rot or both.

1. There is no need wash already clean hands for the sake of protecting your DVDs. If you are that worried about getting fingerprints on your discs, wear gloves.

2. Mold and fungus does not grow without water.

3. All the cases do is protect your discs from dust and make them easier to store or transport. DVD cases are not air tight or water tight. Water or humidity can still get in.

I have mold allergies and a close family member died from a fungal infection of the lungs, but I still worry much less than you do about molds and fungi. Get help for your mold phobia.
