Thread: General Electric showed 1TB holographic disk

At the conference Emerging Tech, held in Boston, General Electric has announced a 1TB holographic disc the size of a regular DVD-ROM, which can be read by a modified Blu-Ray player.

New technology developed by GE, will be used to create a 1TB drives for backup. General Electric expects that the new product appear on the market within the next two to three years, and it will take at least two years before it becomes accessible to ordinary users. GE says that the disk made of new technology; it will be possible to write full-length 3D-movie in high quality, one that can not be recorded on the modern Blu-Ray disc. Holographic discs will have access time is 3ms and the speed of data transmission at five times greater than that of DVD-ROM drive. In the holographic disk using a hologram, the image data that is stored in layers of the disc the size of a DVD-ROM. Drive shared by a laser beam on the reference beam and signal beam, which is encoded data. By crossing the two beams creates an interference pattern, mikrogologramma, which is stored on disk.

Previous versions of the holographic disc used for recording one frame, millions of bits placed in a variety of points of the disc. GE developers were able to significantly reduce the amount of space required to record a single frame, that is, the new discs can store more data per unit area, in addition, they are quite easy to read. The upper layers of data can be read by a standard Blu-Ray player, and a slight increase in the range of tracking Blu-Ray player will be able to read all the layers. GE plans to license the technology for the production of discs and drives for them. Lorraine Peter (Peter Lorraine), manager of the laboratory of Applied Optics, GE, said at the conference Emerging Tech, that the announcement of the license can be expected in the near future.
