Temp and humidity for storage optical media?

[gamemaniaco1987]

For long-term storage of optical DVD / MDisc discs and electronic devices is it better to store at a humidity of 65-70% at a temperature of 31-32ºC or at a lower humidity of 55-60% and at a high temperature of 32-33ºC? my dehumidifier device cannot keep temperature and humidity low at the same time

If we're only talking a degree difference in temperature, I'd go with the lower humidity.

most damaging to DVD disc high humidity 70% or high temperature 33ºC?

[Ian]

I would say temperature but, in both of your cases, the temp is pretty high. Is a degree going to make a big difference?

i live in the northeastern region of Brazil with temperatures between 30 and 35º, is the dvd disc more affected by high temperature or high humidity? if i don't use the dehumidifier the temperature is lower 1 degree but the humidity is higher 60-70%
