Welcome to the Holographic Versatile Disk Industry Blog

Welcome to the Holographic Versatile Disk HVD Industry Blog.
The Plugtek.com welcomes you to the ongoing advancements
of the Holographic Media industry. Soon there will be HVD computer storage that will fit 500,000 300 page books,
63 times the size of a DVD, 6 days of continual televsion recording... All on ONE Disk! the size of the previous PC floppies.

Holographic storage: 500GB

In holographic storage, a laser beam is split by a mirror. One of the split beams has data encoded into it. The two beams are then recombined in a medium that records their interference pattern. This pattern can be read back and decoded into the original data. Since data is literally encoded in beams of light and in three dimensions, data densities are incredibly high.

The first products will be commercial archival storage cartridges that will hold 300GB. By 2008, capacity should be at 800GB.

InPhase is hoping that its first consumer product will be a postage stamp-size card that holds from 4GB to 8GB (no customers for this product have been announced yet). After that, a business card-size piece of film could be produced that holds 500GB.

These card-based holographic storage units should be cheap to produce and operate under low power, since they don't have to spin the media like a magnetic or optical disk does (they use tiny mirrors, instead, to modulate the laser). The drives use standard CD-class lasers, too, which are available in abundance.

InPhase to ship 300GB holographic drive

InPhase has announced that its Tapestry drives will be available this year, using media developed in partnership with Hitachi Maxell. According to the company, the 130 mm discs will have a transfer rate of 20 megabytes per second, making them usable for media applications. Now if only we didn't have to wait another three years for InPhase's promised terabyte discs.
