The Basics of Holographic Storage Holography is an imaging technique in which an object is imaged such that it appears three-dimensional (3D) when viewed later. This is the fundamental technique for producing holograms that are largely used in a range of fields such as data storage, security, art, etc. This article explores the prospects of holographic storage of data. Why is There a Need for Holographic Storage? Archival storage forms a crucial part of the potential of any enterprise to fulfill compliance demands and address litigation issues. But deep archiving has been difficult to date. Although tapes can be removed and secured, it leads to concerns with readability and long-term reliability.
