If I handle DVD-R and MDisc DVD media inside a room and out of the room someone makes use of muriatic acid this muriatic acid will evaporate it will change the ambient air and this muriatic acid will deposit in these media and penetrate inside these media and goes to the damaging internal reflective metal layer?

I had to look this up, no idea what it was.

... and it's hydrochloric acid.

So if you have that in the air, you have bigger problems. The media will outlast you. You may as well ask about media longevity if the atmosphere disappears, or if the planet is hit by an asteroid. You won't be around to care.

As a Brit would say: "Are you taking the piss?"

Yes is the muriatic hydrochloric acid it evaporates when used and penetrates into the dvd-r and mdisc dvd disc eating the reflective metal layer and the dye?

muriatic, aka: hydrochloric, acid in the air is generally not good for anything other than cleaning/preparing surfaces such as concrete for painting. How bad it is depends on the concentration (e.g., PPM) and what else might be in the air. There is no way we can predict the effect on usable life of media beyond that it will shortening it.

Evaporation of hydrochloric acid and 70% trichloroacetic acid modifies the ambient air and penetrates into the CD and DVD and MDisc DVD layers reducing the life of the metal layers? Is this statement correct?

-- merged --

In MDisc DVD or DVD disc the metal layers are exposed and contact to the outside air and external environment in contact with any acid vapor or impurity?? Evaporation of hydrochloric acid and 70% trichloroacetic acid vapor this acids and impurities enter the disc through polycarbonate and glue?

I suggest not storing your discs in any environment that includes periodic spills of caustic liquids or gases.
Add to this list of bad storage locations with a high risk of potential damage:
  1. Center lane of the Autobahn
  2. Nuclear reactor containment vessels
  3. Blast furnaces
  4. Lava flows
  5. Anywhere near Hillary Clinton
I refer to an earlier post suggesting launching your discs into geostationary orbit.

I'm not sure that would work either, what with having to withstand the radiation from the Van Allen Belt.

The question is moot because those vapors will do you in too, quicker than the discs!
