Thanked 15 Times in 14 Posts
currently I have read on the web many sites the information that there are fungi ( example Geotrichum Candidum) that eat and degrade polycarbonate, eat dye, eat glue, eat reflective layer of CDr / DVDr / MDisc contains polycarbonate/glue/dye this information is true or false? Have analysis of scientists how to avoid this problem of longterm storage? I always wash my hands before handling cd / dvd / mdisc but the fingerprints stay in the center and edge of the disc this gerate fungi?

Is there such a possibility develop attack fungi on CD / DVD / MDisc?

I answered you here: http://www.tvpast.org/forum/video-te...t-optical.html

The answer is still no.

Contaminants for optical are (mostly) no different than contaminants for anything else: mud, dirt, bugs, boogers, dog hair, etc. Except to permeate the DVD bonding, it must be tiny. I doubt anything will penetrate the outer polycarb layers. The main issue is contaminants when manufactured.

This is too many long words for tonight.

I understood, fungi and contaminants only attack organic things like dye and not glue and polycarbonate thanks for your help

Some Lime in contact with the dvd / cd / bluray / mdisc degrades and corrode the polycarbonate and glue, Lime is used in wall paints

I suggest you not use wall paint on your discs.

Yes, jitter can get worse over time. That's one way you see longevity fail.
