Heat-Assisted Magnetic Recording (HAMR)
HAMR is an emerging technology enabling ultra-dense storage of digital information. It promises to usher in the next generation of ultra-high capacity data storage devices, expanding the current computer hard disk drive (HDD) capabilities by a factor of 10 to 16. There is an urgent need for such data storage systems, as the rate of digital content creation is exploding world-wide.
A major challenge hindering commercialization of HAMR has been the lack of a robust nanoscale heating system, whose function is to locally and transiently raise the temperature of resilient magnetic materials used for HAMR, facilitating data recording. Such a system must be able to focus a laser beam onto a small enough region of the data storage medium (so that bits of data occupy the smallest area possible), while withstanding the thermal and mechanical stresses of prolonged operation.
NMTI has designed a nanoscale heating system for HAMR using Titanium Nitride (TiN) - a hard, refractory ceramic - as its plasmonic1 component. This system features a light-focusing plasmonic nanoantenna, fabricated from TiN, and it incorporates additional proprietary material solutions ensuring its longevity in the harsh environment of HAMR. We expect the introduction of this advanced nano-heating system to have a major impact on HAMR technology, expediting its commercialization.Learn more ...
Thermophotovoltaics (TPV) is an emerging technology that uses
to generate electric power. The applications of TPV include:
We are currently developing a functional S/TPV prototype using our proprietary broad-band solar radiation absorber/spectrally-selective infrared (IR) radiation emitter system. It is designed to withstand prolonged exposure to temperatures in the range 1000-1500 oC, required for reliable operation of S/TPV systems with low-bandgap PV cells.
We seek collaboration with parties (including PV cells manufacturers), interested in TPV prototype specifications formulation, co-development and testing. For further details please contact us at firstname.lastname@example.org.Learn more ...
