Fuji Photo Film USA, Inc. has recently announced a significant breakthrough in magnetic recording media technology that will exponentially increase the capacity of magnetic media.
The breakthrough, dubbed Nano Cubic technology, is an ultra-thin layer coating that results in higher resolution for recording digital data, ultra-low noise and high signal-to-noise ratios for use on magneto-resistive (MR) heads.
It is reportedly capable of catapulting data cartridge and digital videotape to one-terabyte native (uncompressed) capacities and floppy disk capacities to three gigabytes. To help visualise the potential, 1TB can store up to 200 two-hour movies.
Nano Cubic coating technology can be applied cost-effectively to a mass production manufacturing process while requiring only small modifications to current coating equipment for application.
Fujifilm is beginning to work with drive manufacturers to develop new, high capacity magnetic storage products using Nano Cubic technology.
Nano Cubic technology is said to employ an advanced precision coating process that can control the thickness of the magnetic layer on a nanometer scale. Two types of magnetic particles were developed for Nano Cubic technology, both tens of nanometers in size: acicular ferromagnetic alloy particle and tabular ferromagnetic hexagonal barium ferrite particle.
Dispersion is achieved by using an organic binder material that has the ability to thoroughly disperse the particles in the coating solution so that a uniformly packed structure of the layer is realised.
Applications in development include: magnetic storage tape, both for helical scan and linear recording formats; high-capacity floppy disks; high-definition, long-duration digital video tape for broadcast and home use; and data and video storage tape for home network servers.
