compared a dvd-r disc Verbatim AZO x dvd-r Philips cmc how many years old they can resist and store files? the dye degrades and the reflective layer degrades

You're not seeing complete picture. The dye alone is not the main factor. A factor, yes, but not the only one.

CMC uses an azoic dye as well. But the problem comes from poor QC and inferior bonding glues. Verbatim doesn't cheap out like CMC does.

Ritek used to cheap out even worse than CMC, but has since come to its senses.

Reflective layer does not degrade. I don't where you're getting this. Certainly not this site.

Given all this, your questions come across as nonsense.

the glue of azo Verbatim is better than glue philips CMC? the glue is the main factor for the durability of dvd-r? the reflective layer does not degrade? from what I read the reflective layer is organic as the dye is also

You read wrong. The reflective layer is polycartbonate plastic and the underside of the layer is coated with aluminum.

Your questions were already answered, answered several times here and in other forums, and the answers haven't changed. Why do you keep repeating the same questions? What's your problem?

If you don't like the recommended Verbatim AZO DVD-R, buy something else.

1 the aluminum dvd-r is organic? the plastic is not organic, has disks that use gold and silver not aluminum

2 I like Verbatim, I just want to better understand the composition of dvd-r

3 which is the glue that Verbatim AZO use? which glue the Philips CMC Magnetics cmc mag m01

@gamemaniaco:
- Verbatim glue/bonding is better than CMC, yes. We've already been over this.
- There is no such animal as "aluminum dvd-r". I have no idea where you're getting that.
- Buy Verbatim. It's the best you can buy. The end.

@sanlyn:
Yeah, I don't get it either. There's nothing inherently worse about Brazil. The humidity isn't any worse than many places in the U.S., including my home state of Texas. It's often hot as hell in the summer, and so humid that you can feel the water in the air. My discs are fine. I store them in a temperature-controlled home or office. The only time you find humidity issues is when you store discs in a garage, barn, attic, or other stupid place.

1 CMC manufactures DVD-R for Verbatim, which is the glue used in this DVD? is the bad glue CMC or is it glue?

2 I can not control the humidity and temperature to store the DVDs, I live in northeastern Brazil and here is hot as Texas and in the rainy season the humidity rises too

CMC = bad
Verbatim = good

Store the discs in your home, not outside. You have air conditioning, correct? More important than temperature adjustment, it also helps remove a lot of moisture from the air. So the humidity outside is not at all the same as the humidity inside.

If you don't have air conditioning, yeah, you're screwed, your DVDs will die early. (So will everything else you own.)

I do not have air conditioning

I do not have air conditioning, what to do?

Aside from getting A/C, there's nothing you can do about this.

If I do not have air conditioning dvd-r verbatim will have a reduced durability of a few years?

Yep. All media will -- discs, tapes, hard drives, etc. Pretty much everything you own has a reduced lifespan, be it plastic dishes in the cupboard or your computer. Them's the breaks, I guess.

Just buy the best you can, and cross your fingers. The sooner it gets to a temp-controlled environment, the better it will be.

which temperature is good to store dvd-r verbatim without losing useful life?

Ideal is 60-70F. 75-80F at most.
Humidity (RH) under 50%

Moisture is worse than the heat. Perhaps you need to invest in silica gel.

the temperature here can reach 45 degrees

what is 60-70F. 75-80F? how many degrees?

F = Fahrenheit. That's what the U.S. uses. See http://en.wikipedia.org/wiki/Fahrenheit
Use Google to find Celsius/Centigrade numbers.

the temperature supported a maximum of 26.67 ° C, above that which occurs with the dvd-r verbatim? I do not have to control the temperature, it oscillates night and day

You Must Use Gold Disc TO Resist Against The Humidity And Tempretur That Would Not Be Cheap Disc .

Gold doesn't do anything for humidity (or anything else). The bonding goes first.
Glue + humidity = comes apart
