Holographic memory is developing technology that has promised to revolutionaries the
storage systems. It can store data upto 1 Tb in a sugar cube sized crystal. Data from more
than 1000 CDs can fit into a holographic memory System. Most of the computer hard
drives available today can hold only 10 to 40 GB of data, a small fraction of what
holographic memory system can hold. Conventional memories use only the surface to
store the data. But holographic data storage systems use the volume to store data. It has
more advantages than conventional storage systems. It is based on the principle of
holography. Scientist Pieter J. van Heerden first proposed the idea of holographic (three-
dimensional) storage in the early 1960s. A decade later, scientists at RCA Laboratories
demonstrated the technology by recording 500 holograms in an iron-doped lithium-
niobate crystal and 550 holograms of high-resolution images in a light-sensitive polymer
material. The lack of cheap parts and the advancement of magnetic and semiconductor
memories placed the development of holographic data storage on hold.

Description: Holographic Memory is to use holographic technology to achieve the principle of data records. This concept is Dennis Gabor in 1984 to improve the resolution of electron microscopy made of. His biggest advantage is the high density, only that, Holographic Memory also has great potential to improve, as long as the controller chip has a sufficiently strong data processing capabilities, Holographic Memory techniques can even provide up to 1000TB of capacity. In contrast, the current maximum capacity of the hard disk only 2TB, the Holographic Memory capacity is only equivalent to the "cube candy" offered by a small fragment of storage capacity.
