I've got dozens of "old" backup CD's and DVD's. The "latest", "good" ones are kept separately (including double copies, encrypted, off-site). Due to probably irrational thinking, I'm reluctant to trash the old backups (postponing that day, which will surely come...)
My question is, all other factors being equal, will they deteriorate any faster if I just stack them together without cases, for instance on a spindle, instead of keeping them in separate cases? (I've already got some doubled up in cases).
Any opinions on this would be appreciated.
