mistubishi mam gold DVD-R for archival. shelf life is projected to be 300 years in environmentally controlled storage. tests with lots of humidity and heat cycling have shown very low error rates for a projected 100 years. I still shoot primarily with film, but there's no sense in ignoring digital archival if you have good scans.
