English

Subject field(s)
  • Computer Memories
DEF

A storage device that records binary information in the form of holograms, which are produced (as interference patterns) on photographic or photochromic media by means of laser beams, and are read by means of low-power laser beams.

CONT

Holographic memory offers the possibility of storing 1 terabyte (TB) of data in a sugar-cube-sized crystal. A terabyte of data equals 1,000 gigabytes, 1 million megabytes or 1 trillion bytes. Data from more than 1,000 CDs could fit on a holographic memory system. Most computer hard drives only hold 10 to 40 GB of data, a small fraction of what a holographic memory system might hold.
