Fujifilm achieves highest capacity storage media with advanced prototype tape
“With high performance computing and cloud storage services on the rise, this data density achievement is significant,” said Norio Shibata, corporate vice president, FUJIFILM Corporation, Recording Media Products Division. “Fujifilm and IBM are leading technology development companies committed to advance tape technology to meet the growing data requirements and position tape as the medium of choice for archival storage.”
This record breaking demonstration was achieved using an advanced prototype tape incorporating NANOCUBIC technology developed by Fujifilm, with advanced tape-drive technologies developed by IBM.
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 increase perpendicular oriented ratio. Perpendicular orientation technology with BaFe produces high signal to noise ratio and better frequency response. Enhanced NANO coating technology with super smooth non-magnetic layer controls tape surface roughness and achieves smooth surface of magnetic layer for high signal output. Fujifilm's advanced servo writing technology decreases high frequency disturbance of servo tracks and enables a higher track density.
IBM researchers developed new technologies, including:
- 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.
Fujifilm will continue to lead the development of large capacity data storage media with BaFe technology to provide a cost-effective archival solution to preserve digital data.
