Holographic breakthrough crams in 0.5TB per square inch

InPhase Technologies claims to have broken the record for the highest data density of any commercial storage technology after successfully recording 515Gb of data per square inch.

Holographic storage can dramatically boost capacity as it takes advantage of volumetric efficiencies rather than recording only on the surface of the material.

Densities in holography are achieved by different factors to magnetic storage. Density depends on the number of pixels/bits in a page of data, the number of pages stored in a particular volumetric location, the dynamic range of the recording material, the thickness of the material, and the wavelength of the recording laser.
