Fujifilm announced a technological breakthrough that will allow it to construct a massive 400 terabyte tape cartridge by the end of the decade.
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).
BaFe coatings have for generations become smaller and smaller, allowing for greater storage capacities. But researchers say they have now reached a point where particles have become too small to be read reliably.
Progress in storage tape capacity follows roughly the same principle as Moore’s Law, which accurately predicted for decades that the number of transistors on a chip will double every one-and-a-half to two years. Likewise, tape storage capacities roughly double every two-and-a-half years.
