Holographic data storage
Tokyo-based optware corporation, a leading developer of holographic versatile disc (hvd) storage products, has developed a system – referred to as collinear holography – in which the reference and information beams are handled as a pencil of coaxial light, rather than the two-beam interference method widely used in the past.
- Holographic data storage abstract devices that use light to store and read data have been the backbone of data storage for nearly two decades.
- Ever since there has been a need to store the data files like audio, video, images, etc, a number of storage-devices are evolved though there are various magnetic devices (tapes, floppy, hard drives) as well as optical devices (cd, dvd, blu-ray discs), certain limitations bind them.
