Do you speak as an expert, from experience, or from hearsay?
In my experience RW technology loses data. I have not experienced
data loss with just a writable CD. (Except in the case of
physical damage to the medium, that is.) I've seen an RW get
data corruption in 3years of sitting on a shelf. I have yet
to see a writable CDROM lose data.

Always good advice. Also away from moisture. I dunno whether enough
UV exits a fluorescent lamp, but I keep mine in the dark since I have
them in my home.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
