A german magazine has exposed DVD media to UV irradiation. The amount of irradiation equaled about 20 days of exposure to direct sunlight in germany (meaning, for spain, california, or even australia, it would equal less than 20 days...).
The following discs were not even recognised any longer (no manufacturer IDs mentioned. For some discs, it's clear who made them, for some it's not):
- princo dvd-r
- intenso dvd-r (digital disc dessau?)
The following discs were recognised, but crap afterwards
- verbatim dvd+r
- intenso dvd+r
- sony dvd+r
- tdk dvd+r
- maxell dvd+r
The following discs did not suffer damage at all / did not suffer significant damage:
- verbatim dvd-r
- maxell dvd-r
- tdk dvd-r
- traxdata dvd-r (probably ritek g03, certainly not Vivastar!)
Appearently, Mitsubishi uses different dyes for dvd- and dvd+, because only this could explain why their dvd+r died, whereas their dvd-r didn't.
As you can see, using crap dvd-r is a bad idea. Not only for compatibility...
