holographic data storage

Turning holographic data storage into a product has been a struggle.

Holographic data storage can provide companies a method to preserve and archive information.

These two diagrams show how information is stored and retrieved in a holographic data storage system.

His past research had focused on optical computing, holographic data storage, and neural networks.

Since it involves no moving parts, holographic data storage will be far more reliable than existing hard disk technologies.

Holographic data storage - either still in development, or available but generally only encountered in niche usage as of 2007.

The effect can be used to store temporary, erasable holograms and is useful for holographic data storage.

Holographic data storage is a technique that can store information at high density inside crystals or photopolymers.

He is also well known for his past work in holography, especially with regards to optical computing, holographic data storage, and neural networks.

Holographic data storage.

Holographic data storage contains information using an optical interference pattern within a thick, photosensitive optical material.

The lack of cheap parts and the advancement of magnetic and semiconductor memories placed the development of holographic data storage on hold.

But although the space-saving advantages of holography have been known for four decades, manufacturers have not been able to produce an affordable holographic data storage system.

Early holographic data storage devices will have capacities of 125 GB and transfer rates of about 40 MB per second.

The key to making the holographic data storage system work is the second laser beam which is fired at the crystal to retrieve a page of data.

Holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same area utilizing light at different angles.

Holographic data storage is a potential technology in the area of high-capacity data storage currently dominated by magnetic and conventional optical data storage.

The writing process may use the same kinds of media that are used in other types of holographic data storage, and may use 2-photon processes to form the holograms.

Prototypes developed by Lucent and IBM differ slightly, but most holographic data storage systems (HDSS) are based on the same concept.

In the case of holographic data storage, the beam has some kind information encoded into it (for instance, it can be sent through a transparency or a spatial light modulator).

SLMs are used extensively in holographic data storage setups to encode information into a laser beam in exactly the same way as a transparency does for an overhead projector.

Emerging technologies such as holographic data storage and 3D optical data storage aim to use entirely different data storage methods, but these products are in development and are not yet widely available.

Some have speculated that Nintendo will be the first video game console maker to implement holographic data storage due to the uncovering of a Joint Research Agreement between InPhase and Nintendo.

Holographic memory devices for holographic data storage where the Bragg selectivity is used to multiplex several holograms in one piece of holographic recording material using effectively the third dimension of the storage material.

While many holographic data storage models have used "page-based" storage, where each recorded hologram holds a large amount of data, more recent research into using submicrometre-sized "microholograms" has resulted in several potential 3D optical data storage solutions.
