HDV+-+holographic+disks

This technology was first used by Maxell. The current technology allows for 300Gigabyte storage space with a transfer rate of 20mB/s. HDV stands for //Holographic Versatile Disc.// Maxell has stated that this is only the beginning and that this technology is capable of much more. Maxell expects this storage format to lead the way by being the cheapest source of removable storage space per gigabyte. They have not yet stated when the technology will be on the market for consumers.

//'Holographic recording technology utilizes intersecting signal and reference laser beams to store data in a number of 3D hologram images capable of saving hundreds of data pages in a single location. One 5? inch-diameter optical disc can store up to 150 million pages -- more than 63 times the capacity of DVD. Also, with holographic recording, a multiple of form factors, such as discs, cards, etc, and laser wavelengths (red, green, and blue) can be used.'// explained //NE Asia Online//.

//"Unlike other technologies that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light. This enables transfer rates significantly higher than current optical storage devices,"// said Liz Murphy, vice president of marketing for //InPhase Technologies//.

//"Holographic media makes it possible for millions of pages of information and high-definition images to be held on one small, relatively inexpensive disc,"// said Steven Pofcher, senior marketing manager at //Maxell//.
