Today Fujifilm Recording Media U.S.A., Inc. announce that, in conjunction with IBM, it has developed the highest capacity storage media ever achieved. This advanced prototype media is a magnetic particulate tape that has an areal data density of 123 billion bits per square inch. A single cartridge can store up to 220TB of uncompressed data.
Today Fujifilm Recording Media U.S.A., Inc. announce that, in conjunction with IBM, it has developed the highest capacity storage media ever achieved. This advanced prototype media is a magnetic particulate tape that has an areal data density of 123 billion bits per square inch. A single cartridge can store up to 220TB of uncompressed data.
With the massive data growth over the past few years that is only going to increase, both capacity and density increases are going to be necessary in order to keep up. This milestone, which surpasses Fujifilm and IBM’s previous milestones of 154TB and 35TB, will meet the growing demands while keeping tape a viable option for archived data.
This achievement was made possible by Fujifilm’s NANOCUBIC technology along with technological enhancements from IBM. Here is a quote on Fujifilm’s and IBM’s technology:
“Fujifilm’s NANOCUBIC technology is enhanced to increase recording density by decreasing the magnetic particle size that is essential for high recording density. Fujifilm’s original BaFe synthesis method increases the uniformity of BaFe particle size and decreases 25% of the switching field distribution (SFD), which is an important magnetic parameter for high density recording. The lower SFD leads to a high quality signal output due to the uniform magnetic property of each recorded bit. To ensure the stability of the ultra-fine BaFe particles, Fujifilm improved the magnetic coercivity, yielding an archival life of over 30 years.
A highly controlled dispersion process and newly developed chemical compound allows the BaFe particles to separate and disperse more uniformly and increases the perpendicular oriented ratio. Perpendicular orientation technology with BaFe produces a high signal to noise ratio and better frequency response. Enhanced NANO coating technology with a very smooth non-magnetic layer controls the tape surface roughness, providing a smooth magnetic layer for higher signal output. Fujifilm’s advanced servo writing technology decreases high frequency vibration of the servo tracks and enables a higher track density due to more precisely placed servo tracks.
IBM Technology Enhancements
- A set of advanced servo control technologies that enable more accurate head positioning and increased track density.
- An enhanced write field head technology that enables the use of much finer barium ferrite particles.
- Innovative signal-processing algorithms for the data channel that enable reliable operation with an ultra-narrow 90nm wide giant magnetoresistive (GMR) reader.”
