Successfully manufactured 300 GB 3-way optical disc

InPhase Technologies has successfully built a storage optical disc that has 60 times the capacity of current DVDs and InPhase Technologies will commercialize this huge capacity disc in 2006.

This is a type of Holographic optical disc that creates true 3D holograms, has a storage capacity of up to 300 GB and has a read-write durability 10 times faster than current DVDs.

Liz Murphy, an InPhase spokesman, said that InPhase's Holographic burning technology is completely different from all current DVD burning technologies. While the old technology was only able to record 1 bit of data at the same time, Holographic 3-dimensional recording technology allowed millions of bits of data to be recorded simultaneously at the same time.

This Holographic 3-dimensional disc is about 13 centimeters in diameter, slightly wider than today's conventional DVDs. It contains data in a single crystal material using lasers to ionize the recording material. A single laser light will be split into many other laser beams to perform simultaneous data recording. Another laser structure dedicated to reading data will be able to combine the data that is scorched into a unified data block according to the information coding scheme of Holographic technology.

Experts say that this holographic 3-dimensional technology is much more modern than the newer DVD standards that are battling hard today like HD DVD and Blu-ray DVD. But it is unclear what its price and practical application level will be when it is officially launched.
