Holographic Memory

by Tandle Sneha

Data storage systems are frequently looking for high data volume density and rapid data exchange rates. Magnetic and optical data storage technologies are the two basic kinds. The increaseduse of optical technologies is due to their support for greater data transfer rates. Holographic memory, an optical data storage device, provides these two features rapid data transfer rates and high data densities. In order to attain such high data densities and transfer speeds, components such the spatial light modulator (SLM), lenses, charge coupled device (CCD), and multiplexing agent utilized, Consider the Holographic Versatile Disc is an illustration of holographic memory (HVD). This disc's complete volume contains. Holographic data storage may someday replace magnetic and conventional opticalstorage as the standard technique for highcapacity data storage. Crystals can store high-density data using holographic memory. A sugar cube-sized crystal can hold up to 1 TB of data. 1,000 CDs cannot hold the amount of data that a
