Max temperature to preserve optical discs long-term?

[samus87]

I have DVD + R 16x Philips ID: CMC MAG M01 stored in a temperature of 35.3 C ° every day and humidity 50-62%, approximately how years old this dvdr disc has a useful life durability at this temperature of 35 degrees?

I used my hygrometer for had measured temperature and room humidity

So at the same site as the Cuban cigars?
but rather as humidity 72-77% would be better

CD + DVD is stored cool, no light .... 20 degree C
or Fahrenheit = 86 Degree
or Réaumur = 16 Degree

humidity max 25%
lying flat in cover

35.4 degree temperature is bad to preserve the long-term dvdr discs? this temperature of 35 degrees how many years of useful life these discs will have?

What is the temperature and humidity recommended for all optical disc manufacturers of DVD + R for long-term storage?

Can anyone help me with this doubt?

Your media isn't going to last very long at that temp and humidity. It's too hot and wet. It needs to be under 50% RH and under 80(F) / 27(C).

Also, the lower the better, though you still need some RH% present and it needs to not be cold. There is a such thing as too "unhumid" and too cold. I think the RH% minimum is something like 10-15%, and the coolness needs to be above about 65(F).

No light.

Lordsmurf thanks for your help

for 3 days I used a digital hygrometer to measure humidity and temperature in the compartment where they are the dvdr discs

the temperature ranges from 29.6 ° C ~ 35 C ° and the humidity ranges from 39% ~ 61%

with this data which estimated useful lifetime for my DVD + R?

A decade, maybe. You may still lose a few discs -- especially anything non-premium (CMC, etc). The issue with longevity is that the discs slowly go out of spec. In other words, the drives have a harder time reading the data. There data is usually still there, but it may be hard or even impossible to access at some point.

Your RH%/temp is like me storing discs in the outdoor storage shed. And that's how you DIY accelerated aging tests.

1 you believe these my discs dvd + r philips CMC mag m01 in these conditions that I spoke will have an expected useful life of 10 years? when in 8 years I will make a new burning in mdisc or dvd verbatim

*2 you said the recommended temperature is 25 degrees long therm storage, with this increased temperature at + 10 degrees (35 C °), the estimated time of useful life dvdr disc to fall down as %?

[lordsmurf]

If the data matters, then you should make a burn on Verbatim now.

M-Disc is just marketing hype. The media isn't great.

Higher temps and higher humidity (RH%) will severely reduce lifespan. The number I gave were an approximate max for semi-safe storage. It's not an ideal condition. Again, high temps and RH% are how you DIY accelerated aging tests. That should tell you something.

1 recommended is 25 degrees C and 50% humidity in these conditions a DVD + R Philips CMC MAG M01 will have an expected useful life of how many years?

2 25+10 = 35 degrees Cº alternating between 29.6 and 35.4 and humidity alternating between 39% and 66%, which will be the useful life expectancy of the DVD + R in these conditions?

it is true that an increase in temperature at 10 degrees above 25 degrees C ° reduces to half (50%) the estimated lifetime in years for the DVD + R? this information is true or false?
