I agree. That is something I've read about, but I haven't tried yet.
I'm not convinced, however, that that would allow recovery of data from
an old DVD (20 yr old) as too much would be damaged in too many places.
I'll be ordering some 'gold' DVD's shortly for archival purposes and I
might double down my bets with RAR/PAR2. My 120 scans run 500 MB each,
so I only get 9 images per DVD. On the other hand I only get one or two
really great images per roll of 120...
