Created 500 GB microholographic disc
A group of scientists from the Berlin Optics Institute and the Faculty of Optical Technology at the Berlin University of Technology found a way to burn 500 GB of information onto a disc the size of a regular DVD.
Researchers in the Microholas Project group used a micro-holography method for recording, which allows them to record data in nanostructures. In contrast to the usual recording on CD or DVD (produced by the laser flash), the new technology allows you to create three-dimensional holographic grids with which you can write and read data on the physical structure of the disk.
Micro-holographic discs are exactly the same size as regular CDs and DVDs, but unlike them they are capable of storing data on 10 layers. Presented disc prototypes are capable of supporting write speeds of up to 50 Mbps. According to the developers, by 2010 they plan to create an “improved device” with the ability to store 1 TB of information and data transfer speeds of up to 200 Mbps.
The applied application of the technology is still practically unreal. Firstly, because of the too high cost of creating microholographic discs and, secondly, due to the fact that the reserve of HD-DVD and Blu-ray discs is not exhausted. But German scientists are not losing their enthusiasm and continue to look for ways to interest large carriers in their development.
