Fujifilm announced a technological breakthrough that will allow it to construct a massive 400 terabyte tape cartridge by the end of the decade.

Tape drives currently top out at about 12 terabytes of storage.

The Blocks and Files web site reported that Fujifilm says it can achieve the newer, greater capacities by switching from the standard Barium Ferrite (BaFe) tape coatings to Strontium Ferrite (SrFe).
