Company Claims Holographic Disk Breakthrough
 

InPhase Technologies reckons it can squeeze 200 gigabits on a single square inch of optical disk.

Ths company showed off its holographic prototype at the National Association of Broadcasters (NAB) convention in Las Vegas this week

InPhase said is uses a patented polytopic recording method to squeeze 300 gigabytes (GB) capacity on a single disk. It says that by 2009 it will be selling disks with up to 1.6 terabyte (TB) capacity.

Holographic storage delivers high capacity by recording data throughout the volume of the recording material, and not just on the surface, said the company. It says it's new recording technique enables more holograms to be stored in the same volume of material by overlapping not only 'pages', but also 'books' of data.

The recording method is used in conjunction with an optical architecture, which uses optical lenses with a high numerical aperture (NA). The combination of the new recording method and high NA lenses results in a smaller page size that provides a 10X increase in achievable data density, the company said.

It says it can also transfer the data at a rate of 27 megabytes (MB) per second.
