Same thing -- damaged polycarbonate (plastic).

But it is sure that the the area of the dye and reflective layer will be affected or there is some hope that the disc remain good?

Yes. I'm sure. Re-burn it.

The best example I can think of is 9/11, when the towers fell. Even though only some of the metal structure was damaged initially, it's was weaken and cascaded. When a rigid structure is weakened, bad things happen. The Columbia shuttle disaster over Texas is another. One damaged tile caused all that. Same principle here. Plastic, metal, ceramic, or otherwise.

It's science.

Just re-burn it.

1 You know the email from an engineer at CMC Magnetics for me to ask him? does not have any email from engineer of CMC on her website

2 I am in need of DVD + R Dual Layer and here was one who found the disc Nipponic brand, I buy? is reliable and has good durability? seems that Nipponic uses materials Bayer

1. No.
2. For DVD+R DL, use Verbatim and nothing else.

1 is very difficult to find here verbatim, Verbatim DL media you have here are all false, DVD + R DL from Nipponic has some quality and good durability, I do not know who the factories Nipponic but they use materials Bayer

2 There are high quality medias like Taiyo, Mitsui and Verbatim with the same problem of plastic break that occurred with my Philips DVD + R?

Verbatim is best. Use that. If you choose not to, then it's your gamble.

It would be very unusual from TY and Verbatim to have bonding issues, though it can happen rarely.

I apologize and thank you for your help

I will try verbatim although it is very difficult to find the original media, have only fake

you know who is the manufacturer of DVD + R DL Nippponic?

Read the media ID: http://www.digitalfaq.com/forum/medi...a-quality.html

I have not bought the media of Nipponic DVD + R DL 8.5GB so I have no way to verify what the manufacturer, I thought you knew this information, I have already got in contact with nipponic and they do not respond

1 kpmedia what you know about this dye Cyanine dye is bad and easily presents problems with high temperature and humidity and light from lamps or the sun? Here where I live, temperatures drop to 40 degrees at most

2 as is the situation of Cyanine dyes nowadays?

3 kpmedia, as you discovered that my Philips DVD + R 16x AZO dye use and not use Cyanine CMC as the attendant told me? you have a high knowledge

Cyanine based DVD dyes are terrible, but it's not used anyway. You don't have cyanine discs. That was mostly Princo and junk sold in Europe years ago.

If you store optical media in poor temperatures, even the best Taiyo Yuden and Verbatim media, they'll all die prematurely. Think about it -- you "burn" media. If you get it hot again, you can screw up the dye. The bonding (glues) are suspectible to damage from extreme heat and cold too.

Don't store DVDs outside.

The CMC person may work at CMC, but he doesn't know squat about their products. That's not cyanine.

There's really nothing special about Brazil climates. No more so than Texas climates.

1 I still do not understand why the cmc attendant told me via email that my philips dvd + r 16x was cyanine, he said the cmc manufactured dvd + r 8x was AZO rise above 8x was cyanine, how do you know if this identifier philips 16x dvd + r 's rise ? has some feature on the disc ?

2 cmc also the attendant told me that philips 16x dvd discs manufactured by it has a life of 30 years using accelerated testing and stored at a temperature of 25 degrees and humidity of 30-50 % but I can not control the humidity and temperature and they oscillate much here where I live the temperatures here can reach a maximum of 40 degrees and when it rains the humidity is high

my disc: http://www.digitalfaq.com/forum/imag...lips_3_2-1.jpg

The CMC person didn't know what he was talking about. Which is really sad, since he works there. Then again, I'm not surprised. CMC media is mostly crap. It probably is the result of having employees that don't know anything.

thanks admin

1 he (attendent) knows a lot, he gave me lots of information about the coloring but he does not know much and then he ask the engineer what is the dye used in my Philips DVD + R 16x the engineer said it was the Cyanine and that CMC used AZO up to 8x speed and above this speed is Cyanine not know if the epoch in which the disc was manufactured influences the choice of my ing the disc was made in 2010

2 I let this doubt about the dye used in philips dvd + r 16x manufactured by CMC in 2010 to resolve the digitalfaq with you because you guys have a lot of experience and knowledge on optical media

3 on a DVD + R has some element or material that block and prevent entry of moisture, oxygen inside the dvd+r disc?

We've already told you about the CMC disc dye. Either you believe us, or you believe some moron.

The third question is this:
- Don't store DVD underwater.
- Aside from that, a polycarbonate and bonding provides decent protection from the elements. Though the bonding eventually breaks down, and that's one of the ways a disc will die in a few decades. Some have dye turn, others will have bonding issues.

thanks for the help

1 I am not believing what he says, I believe in you, I just wanted to know how you guys manage to differentiate and know which dye is used on a philips dvd cmc

2 cmc using azoic dye on dvd + r 16x since what year? the difference between rise and azoic?

3 glue also protects the dvd and prevents ingress of moisture and oxygen into the disc? my dvd this with a piece of broken plastic in the center of the disc but the disc is glued around

Since around 2004 -- at least 10 years now.
Broken "plastic" (polycarbonate) is not a good thing. I suggest re-burning the disc to one that's 100% perfect.

1 How you found it since 2004, nor the cmc have this information, you are well informed and thanks for the help

2'll burn another disc in a dvd disc in good glue protects and prevents ingress of moisture and oxygen into the disc?

thanks

1 like you found that the cmc uses azo dye in philips dvd + r 16x since 2004? this information can not answer the cmc, cmc uses the philips dvd in the azo or azoic and the difference between them? they do not know anything and are saying that is cyanine but I believe in you the digitalfaq

2 I will buy new dvd discs and burn them exactly as you said, about the glue used on the discs dvd, it really has the ability to block and prevent the entry of moisture, oxygen inside the disc?

3 I keep my discs cd and dvd within a rack and that rack there is a 29'' CRT TV, dvd player and receiver for parabolic antenna, there is some problem such discs are next to these items? this rack is the best place where I can store discs because it is in an open and ventilated room

could someone please answer my thread please? you guys are too busy?

You didn't ask a question.

1- Yes, buy new DVDs for the broken ones. Why are we still discussing this?
2- Yes, the rack is fine.

1 heat generated by the CRT TV 29'', the heat generated by the dvd player and the heat generated by the channel receiver will not heat up the atmosphere and warm the discs and will not affect the lifetime of the CD / DVD even though they were next to these equipment? look the picture and-demonstration

2 you said the cmc magnetics uses azo dye in DVD + R since 2004 and is a partnership with Mitsubishi, as you get this information? the attendant cmc not tell me it just said that the dye on dvd + r 16x philips was cyanine but did not believe him, I believe in you

1- It's fine.
2- Official docs a decade ago.

do not get me wrong, I want to learn with you

1 I'm not talking about 10 years ago but 2010 till today continues today cmc using azo? My discs dvd + r 16x philips were made in 2010

2 from what I learned with you the azo belongs to mitsubishi and verbatim but the cmc has this patent?

3 I thought the burning rate of the disc had everything to do with the dye type used: cyanine 16x and azo 8x this on dvd

We're not either.

CMC in 2004: "Help me Obi-wan, you're my only hope?" (Star Wars)
Mitsubishi in 2004: "Here I come to save the day!" (Mighty Mouse)

It was a fundamental change in everything they did. And as far as everything/everybody I've seen online, it's not changed. It was a complete manufacturing refit that allowed CMC to house MCC production to this day.

For a CMC "tech" to say that it's one dye burned at one speed, and another dye at another speed, is 100% retarded.

Cyanine is not, and never really was, a good dye. It was mostly unstable on DVD-R. It was discard on CD-R 15-20 years ago for "better" dyes (phthalocyanine mostly). How its "better" can be argued, as pure cyanine had the highest readability, though not the best longevity.

A dye CANNOT magically change. Burned or unburned, the dye is always the same.

Thank Lordsmurf , and you have much knowledge about kpmedia medias

1 if the dvd + r 16x philips manufactured by CMC in 2010 in then you would say that the CMC uses azo dye on all your disks ( philips , memorex ) from 2004 until today?

2 the rise of the cmc for philips dvd + r 16x is a pure and legitimate rise of mitsubishi ?

3 is true that Cyanine ceased to be used in any and all CDR DVDR 15 years ago ?

4 the tech told me that the cmc and cmc manufactures philips dvdr with durability for 30 years , is this true or false ?

Lordsmurf please answer my questions previously posted

can someone answer my questions above, please?

Stop begging. We get busy around here -- doing the video work, the web hosting and development work, and answering questions from clients and Premium Members (of which are you are not).

Also stop asking the same questions over and over.

1. It was a fundamental change in how media was made at those manufacturers. It was a better method, thanks to Mitsubishi's help. Yes, sure, they could have changed, but I doubt it. What was true in 2004 appears to still be true in 2014. DVD has been mature since at least 2008, and nothing has change anywhere.

2. This makes no sense.

3. I don't know about 15 years ago, but I've not seen cyanine in probably a decade now.

4. Once burned, and you verify the burn is good, it should be good for at least 30 years. But the problem is getting that good initial burn.

Thaks for help

Sorry I do not wanna let you guys upset , it seems you're always too busy to be premium customer has to pay ?

1 AZO used by CMC DVD + R 16x Philips 2004 until 2014 is a pure and legitimate AZO dye or is it another ? I need to know the name of the dye used in 16 philips dvd + r manufacture cmc, if this Philips DVD + R 16x Cyanine dye wore this disc was convicted to lose the files in a few months or a few years ? I just received an email from the CMC and he said the dye Philips 16x DVD + R is a Cyanine and like and similar to the Cyanine formula used by Sony and Taiyo Yuden

2 I got discs dvd verbatim copies, to make those my DVD + R with a layer of broken plastic and torn in the center of the disc? I have important files burned these discs , what should I do with essses discs ? Should I throw them in the trash or they still are properly to be stored long term and I keep them stored , can someone analyze this problem and tell me if these discs will oxidize or will get moisture and oxygen inside the dvd destroying data layers and reflective ?

photo is example, red is break one layer plastic

Lordsmurf please answer my questions above

Taiyo Yuden does NOT use cyanine. Their DVDs use Azo! Only the CD-R uses "super cyanine" (stabilized cyanine).

There is no Sony media. Sony is a brand name. Once upon a time, Sony outsourced its own media ID to Taiyo Yuden and Dexon. But those days are long gone. Daxon has been out of business since 2008-2009. And Taiyo Yuden hasn't been used since the 8x era -- long before the JVC buyout.

That CMC guy is a moron.

Somebody is confusing CD-R with DVD-R. I almost wonder if somebody has bungled the information found on our own site!

Ritek may have used a cyanine-based dye at one point, back in the RITEKG01-04 era. For example, asymmetrical trimethine cyanine. Here's an old patent document on that dye: http://www.freepatentsonline.com/6306478.html. But I could never find solid proof of this.

The CD-R days were fairly open compared to DVD-R and DVD+R. Information on them was very guarded, so it's not a simple question to answer.

DVD-R uses organic dyes. And while cyanine is an organic dye, there are others. Cyanine has a number of properties that make it a poor choice for optical media. The above patent document even listed some of them.

You're asking questions outside the scope of what this forum is about. We can help you learn which discs are best, why, and where to get them. But you're asking about the chemistry of discs here. That takes more time to answer than any of us are willing to invest. If you want to learn more about the dyes in discs, I suggest you learn some fluent English, learn Japanese, learn chemistry, and start sifting through patent documents from around 1996-2004.

As far as bad discs go, at least re-burn the contents to better media. As far as what you do with old discs, I honestly don't care. We keep many for research, so you can surely do that. But we often toss bad discs in the trash where they belong. What you do is up to you.

/thread

Thanks.

thanks for help

1 I was already thinking that my Philips DVD + R 16x manufactured by CMC in 2010 used the Cyanine and so I thought I would lose all burned files on these disks before long all this because I thought that belonged only to AZO Verbatim and MAM-A, I did not know that CMC Magnetics had the patent for use in AZO DVDs from Philips

2 it is true that Cyanine is only for CD-R? I have some CD-R's SmartBuy purchased in Brazil, they are good and decent?

3 as the manufacturing process of a DVD + R and works as the first layers of plastic is broken during manufacture of the disc? this means that the rest of the disc is not the glue that keeps out oxygen and moisture inside the dvd?

please someone answer my questions

please repply kpmedia

please repply my questions for medias

can someone answer my questions please?

I got a camera and I took some pictures of my DVD + R 16x and I wonder if this problem will result in loss of data on that disk and will get moisture, oxygen and impurities inside the disc hitting the recording layer and the layer reflective

if this problem does not affect the data, I will not be necessary having to burn these files to new disks now, I'll do it a few years later but I need to understand this problem
