How do the laser beams selectively pass through the layers? A layer of dichroic mirrors that exists between the holographic and servo data layer reflects back the blue-green laser beam, letting only the red laser pass through it to reach the servo information. By doing so, it actually eliminates the possible chances of the interference that can happen due to the refraction of blue-green laser off the servo data pits, a problem that had affected the efficiency of many holographic storage media in the past.
Most optical storage devices, such as a standard CD Compact Disc , save one bit per pulse. HVDs manage to store 60, bits per pulse in the same place, in a truncated cone shape, that has a diameter of micrometers at the top and micrometers at the bottom. The HVD Alliance is trying to improve the storage capacity further to touch its dream 3. In addition to HDV, other proprietary standards are making advances optical disk technology. Tapestry Media — a holographic format patented by InPhase Technologies — having a storage capacity of 1.
The biggest challenge for HVD will be in establishing itself in the commercial market, which as of now seems to be a distant dream, given its higher cost margins.
