Holographic storage is a data storage technology that uses light to record information in three dimensions. Unlike traditional storage methods that save data in layers, holographic storage captures data as holograms, allowing for higher storage density and faster access times. This means it can hold much more information in a smaller space. The process involves using lasers to create interference patterns in a photosensitive material, which can later be read by shining a laser on it. This innovative approach has the potential to revolutionize data storage, making it more efficient and capable of handling the growing demand for digital information.
