The Information Age needs a good way to archive information. Something that has very high capacity, that can be stored for a very long time and that can be retrieved easily. Optical discs are not as long-lasting as they would seem, but good old magnetic tape has a lot of potential.

Fujifilm has boosted magnetic tape into something much better. Its new dternity tape uses barium ferrite instead of conventional metal particles to get extremely high information density without oxidation when exposed to air. This is combined with a new coating process that is one-tenth the thickness of magnetic tape. The result is a medium that lasts for decades and has the capacity for today’s immense data volumes – one cartridge can hold as much as 50,000 DVDs. More
