InPhase Technologies Successfully Develops Holographic Storage Discs with 60 Times the Capacity of Current DVDs
InPhase Technologies has successfully created a holographic storage disc that boasts a capacity 60 times greater than that of current DVDs, with plans to commercialize this massive storage medium in 2006.
The holographic disc provides a true three-dimensional imaging effect, with storage capacity reaching up to 300 GB and read-write speeds that are ten times faster than existing DVDs.
According to Liz Murphy, a spokesperson for InPhase, their holographic disc recording technology is fundamentally different from current DVD recording technologies. While traditional methods can only record 1 bit of data at a time, the holographic 3D recording technology allows for millions of bits of data to be recorded simultaneously.
This 3D holographic disc has a diameter of approximately 13 cm, slightly larger than a standard DVD. It stores data in a single crystal material form, utilizing lasers to ionize the recording medium. A single laser beam is split into multiple beams to perform simultaneous data writing. A separate laser structure dedicated to reading data can then recombine the scattered recorded data into a unified data block that accurately reflects the information encoding intended by the holographic technology.
Experts note that this 3D holographic technology is significantly more advanced than the current competing DVD formats, such as HD DVD and Blu-ray. However, the pricing and practical application of this technology upon its official market release remain unclear.
