In response to the rapidly changing face of computing and demand for physically smaller, greater capacity and high bandwidth storage devices, the holographic memory came into existence. Holographic data storage using volume holograms offers high density and fast readout. It can store 1Tb-4Tb of information on a sugar cube sized crystal. That means a single holographic device can replace more than thousands of CD's. This paper provides description about the principle of holography along with the comparisons observed between the conventional optical disks and the holographic disks.
