Burr Research into and the development of data storage devices is a race to keep up with the continuing demand for more capacity, more density, and faster readout rates. An alternative approach for next-generation memories is to store data in three dimensions. This article describes recent developments in holographic 3D memories, in which high density is achieved by superimposing many holograms within the same volume of recording material.
Holographic storage is a promising candidate for next-generation storage.
Recent research has demonstrated that holographic storage systems with desirable properties can be engineered. The next step is to build these systems at costs competitive with those of existing technologies and to optimize the storage media. Computer , Vol.
