Next-Generation Storage

June 26th, 2007 · No Comments

The Economist writes:

A new storage technology, which will go on sale in the next few weeks after years of development, can squeeze more onto a small disc or cartridge than ever before. With the potential to store hundreds of times more data on a disc than today’s DVDs or even the latest high-capacity Blu-ray and HD-DVD discs, holographic storage is about to hit the market.

Unlike DVDs, which store data in thin layers just beneath the surface of the disc, holographic storage encodes information in three dimensions, within the volume of the disc. This will enable the first holographic discs to store a colossal 300 gigabytes of data12 times more than the latest Blu-ray discs and 60 times more than a standard DVD. And within a few years this capacity is expected to increase more than fivefold to 1.6 terabytes (1,600 gigabytes) of dataenough to store five seasons of a television drama, in high-definition video, on one disc. But as is so often the case with new storage formats, rival standards are under development.
