Optimal Media & Methods for High End Archive of 16mm Film Information

I have located a bunch of 16mm film cans, most dating back the the 1930's. Lots of useful stuff, a lot of coverage on Indy car racing from that period, plus some family items found nowhere else. The film is somewhat brittle, though, and I would like to convert it to a high end archival digital media, so it can make it another 80 years OK.

First, what would be the best media to use? Some form of HD? Is optical better than magnetic for this application, and if so, what form of optical? Should this kind of work use a codec like h.264/AVC, or is it better that capture raw frames? Are there any labs out there that specialize in this stuff, that could handle such old film with real TLC?

Any insight is appreciated.

Cheers,
