Holographic Data Storage
18 07 2007Holographic storage delivers high capacity by recording data throughout the volume of the recording material, and not just on the surface. With each flash of the laser, a data page of approximately 1 million bits is recorded. Each data page is located at a unique address within the material and several hundred pages of data, each with their own unique address, are recorded in the same location of the medium. Each of these collections of data pages is then referred to as a “book.” This new recording technique enables more holograms to be stored in the same volume of material by overlapping not only pages, but also books of data. This dramatically increases the storage density.
