400 TB Storage Drives In Our Future: Fujifilm

One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape.

As reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density on tape of 224 Gbit-per-square-inch, which would enable 400 TB drives.
IBM and Sony have already demonstrated 201 Gbit-per-square-inch technology in 2017, with a potential release of the technology for high volume production in 2026. Current drives are over an order of magnitude smaller, at 8 Gbit-per-square-inch, however the delay between research and mass production is quite significant.

Strontium Ferrite would replace Barium Ferrite in current LTO cartridges.

In standard LTO nomenclature, we are currently on LTO-8 where the drives have 12 TB raw capacity.
Current generation LTO-8 cartridges take at least 9h16 to fill, with predicted speeds on future drives increasing that even further.

Prices for current LTO-8 tape are the lowest out of all storage media. Depending on volume, prices around 0.8-1 cent per gigabyte is fairly common. Currently only Sony and Fujifilm are licencees to create LTO-8 media, however other companies such as HPE and IBM resell models under their own brand.

Fujifilm points to 400TB tape cartridge on the horizon

Fujifilm reckons it can build a 400TB tape cartridge using Strontium Ferrite (SrFe) media. This is 33 times larger than the current LTO-8 cartridge and takes us out four more LTO generations to 2028 and beyond
