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.
Holographic memory 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.
