Daewoo Electronics has been quietly working on and it looks like they have completed the first working model of holographic storage device. Byoungbok Kang of Daewoo Electronics explains how the company went about designing the system along with the hurdles they overcame to do so.

According to the article written for National Instruments, Kang states Daewoo's HDDS, or Holographic Digital Data Storage device is comprised of two subsystems which include something called "an electro-optical motion control system based on the National Instruments CompactRIO 3M gate FPGA series and a video decoding system based on an 8M gate Xilinx FPGA board."

Mr. Kang explains best how these components work together...

...The CompactRIO system controls a linear motor, a stepper motor, a galvo mirror, and a CMOS camera. Each motion control loop requires precise control, so we use feedback signals to control and detect data. Unlike a traditional computing board, CompactRIO lets us customize pulse generator timing to the resolution of a single FPGA clock using the NI LabVIEW FPGA Module...

By using hardware in National Instruments' toolbelt Daewoo Electronics was able to complete the working model to be able to working with holographic media. Holographic Digital Data Storage works by projecting 'pages' of data onto the crystalline media by a signal beam and a reference beam, as we explained a story about InPhase Technologies.

There is no word yet on when a commercially available model will be launched or even if a commercial version will be made, but the article gives some insight as to how much it takes to design one of these puppies.
