Six months ago scientist from the Imperial College ,in UK claimed that they invented an optical storage device with 1 TB capacity after wich six companies have come together to announce the development of a similar capacity disk .
This revolutionary technology , holographic versatile disk , is regarded as the next generation of optical disks
after Blu-ray or HD-DVD formats .One of these companis that created the new technology is the famous Fuji Photo.The disk is capable to store up to 200 .avi movies and a 1 Gbps transfer rate . The collinear technology that is behind the optical disk is developed by Tokyo-based Optware . Optware has many partners that helps them in the process of development . Some of them are Japan-based companies CMC Magnetics Corporation , Fuji Photo Film , Pulstec Industrial , Strategic Media Technology and Toagosei.
Holographic Information Storage breaks the density limits of conventional optical storage by recording through the full depth of the medium instead of recording on the surface only. One HVD can store upwards of 200 gigabytes of data, the equivalent of more than 40 of today's DVDs. Future implementations will be able to store more than 1.3 terabytes.
