Holographic disks now a rival for Bluray

Gone are the days of DVD and Bluray here comes Holographic disks with storage upto 300GB..




A Holographic disk is about the size of Dvd which can hold data 60 times more than that of Dvd!!

Can u believe it that there are holographic disks which can hold data upto 300GB..

These disks store information through the interface of light through and a technique known as holographic memory..

Holographic disks were first designed by Inpase Technolgy Inc. located in USA ..

Data can be read and written from these disks @ 10 times faster than normal Dvd's..

The discs, at 13 centimetres across, are a little wider than conventional DVDs, and slightly thicker. Normal DVDs record data by measuring microscopic ridges on the surface of a spinning disc. Two competing successors to the DVD format – Blu-ray and HD-DVD – use the same technique but exploit shorter wavelengths of light to cram more information onto a surface.

Holographic recording also improves the data transfer rate which is now 27MB/sec. It was 20MB/sec.
