300GB Holographic Optical
Disk Introduced by Inphase Technologies
InPhase Technologies announced
that it has demonstrated the highest data density of any commercial technology
by recording 515 gigabits of data per square inch on holographic disc.
Holographic storage is a revolutionary departure from all existing recording
methods because it takes advantage of volumetric efficiencies rather than only
recording on the surface of the material. InPhase will deliver the industry’s
first holographic drive and media later this year.
The first generation drive has a capacity of 300 gigabytes on a single disk
with a 20 megabyte per second transfer rate. The first product will be followed
by a family ranging from 800GB to 1.6 terabyte (TB) capacity. 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
