Much in store
If you haven’t already done so, don't buy that DVD just yet! Two companies – Imation in the US and Bayer in Germany – are developing holographic discs that can store movies, pictures, sounds and computer data. The discs use liquid crystals to create data pages that can be stored within the layers of a hologram.
Imation's “holodiscs" will initially store about 125GB whereas today's DVDs store less than 20GB. The company claims that future versions will have a storage capacity of one terabyte. Imation hopes to have its holographic CD-ROM recorder on store shelves by 2002.
Bayer plans to have its holographic discs, which will store one terabyte, on the market by 2004.
