Holographic advance aids storage
BBC NEWS Holographic advance aids storage A US firm says it has set a
commercial data storage record by achieving 515 gigabits
(Gb) per square inch. InPhase Technologies says it reached the level using a
holographic drive, which has a higher capacity than conventional magnetic
storage media. It said the technology could eventually lead to a holographic
disc that could hold more than 100 DVD-quality movies. InPhase expects to
unveil its first holographic drive later this year, with products of up to 1.6
terabyte coming. More storage Holograms use a three-dimensional image generated
by lasers to store information. The concept has been around for several decades
but the optical storage technology has only become feasible in the last few
years. Chief technology officer Kevin Curtis said previous tests carried out in
April 2005 had only achieved 200Gb per square inch. By comparison, magnetic
disks, such as those used in the hard drives, can manage a storage density of
about 37.5Gb per square inch. "We are particularly pleased at the rate of
improvement," he said. "The latest results from our ongoing tests on
holographic data density have surpassed expectations." InPhase says the
benefits of holographic data storage will include allowing technology managers
to archive data in less space. The first generation of InPhase drives will have
a capacity of 300Gb on a single disk. "The technology represents a potential
alternative to incumbent technologies for archival storage requirements," said
Wolfgang Schlichting at analysts IDC. Story from BBC NEWS:
