Holographic storage to go commercial
will see the début of 500 GB disk drives as standards for holographic
storage and commercial holographic storage products in 2006. Hitachi is looking
to propel its 3.5 inches line of drives (commonly used to store desktop computer
files) into new markets. It plans to ship a hard drive that holds 500 GB of
data by the end of Q1 2005.
Optware will have specifications for its holographic storage technology approved
by an international standards body called Ecma International in 2006. The company
is developing technology that puts 100 GB-1 TB of data, with data transmission
speeds of 100 Mbps-1 Gbps, on discs that are of the same diameter as today's
CDs and DVDs.
Another storage solution provider, InPhase Technologies, has demonstrated the
first fully-functioning prototype of its Tapestry holographic drive at the 2005
Storage Visions conference held in Las Vegas. The company's holographic storage
media stores data in 3-D holograms cut into a polymer material that's 1.5 mm
(0.06 inch) thick and is placed between two 130 mm (5.1-inch) plastic discs.
Since holographic devices are able to store data in 3D 'pages,' they should
have a greater capacity than today's CDs or DVDs that store data only on the
disc's surface (except for dual-layer DVDs-they have two layers of data). By
2009, InPhase hopes to be shipping drives that can store as much as 1.6 TB on
a single disc.
