I hear audio tapes that are older than I'm and they were in a very good
condition and as I said before, I know professional video tapes that
were ruined, because BASF fault during the production of those tapes.
Possible e.g. by lightning, because lightning protection is not safe or
just because of Finagle's law.
IMO for less data DVDRAM is good and for much data HDs are the best
media we could use, of cause those HD drives need to rest, when not in
use. I'm turning on my computer several times a day and my drives get
broken after 2 years.
IIRC somebody wrote that at his school they use HDs to backup, because
of the costs.
