Holographic storage is computer storage that uses laser beams to store computer-generated data in three dimensions. The goal is to store a lot of data in a little bit of space.

Perhaps you have a bank credit card containing a logo in the form of a hologram. The idea is to use this type of technology to store computer information.

Although no one has yet mass-commercialized this technology, many vendors - including Lucent and IBM - are working on it. Prototypes of holographic storage devices can store at least 12 times the amount of information on today's largest magnetic hard disk drives, with input/output rates more than 10 times faster than what is possible today.
