InPhase demonstrates holographic 515 GB per square inch data density

Visualize a single disk sitting near your home theatre with a power to hold 106 DVD movies. Forget Blu-ray, forget HD-DVD, the Holographic data storage has achieved the deftly. Gifting users more space, time, and power, InPhase Technologies, has successfully demonstrated the highest data density of any commercial technology by recording 515 gigabits of data per square inch.

Holographic storage drives will be released later this year. Moving away from traditional methods of data storage, holographic drives uses volumetric efficiencies rather than only recording on the surface of the material and thereby ranging capacity from 800GB to 1.6 TB.

In this demonstration there were over 1.3 million bits per data page, and 320 data pages spaced 0.067 degrees apart were stored in the same volume of material. A collection of data pages is referred to as a book, and InPhase's PolyTopic recording architecture enables more holograms to be stored in the same volume of material by overlapping not only pages, but also books. Three tracks of overlapping books were written with a track pitch of 700 microns. The InPhase Tapestry material was 1.5 millimeters thick, and the laser wavelength was 407 nanometers.
