****Holographic DVDs****
| quote: | Softpedia
Obviously, winning the battle doesn't mean eliminating the competitor, each of the formats already having its supporters and partisans.
But whoever wins the hundreds and thousands of billion of dollars and whoever remains on the side, we can't possibly know yet, especially since...
The war is futile
... because both formats, so debated since the beginning of 2004, may find themselves outrun by the Holographic Versatile Disc (HVD).
While Blu-Ray and HD-DVD use the same laser, other producers thought of combining the two lasers (red and blue), in a single ray and thanks to Optware , on a disc the size of a CD or DVD, 1 TB of data could be stored (20 times more than on a Blu-Ray disc), with a transfer rate of 1 Gbit/s.
The format is developed by the Japanese company Optware, in collaboration with Fuji Photo and CMC Magnetics. The three companies allied with Nippon Paint, Pulstec Industrial and Toagosei and "HVD Alliance" was born.
The problem is that, while Blu-Ray and HD-DVD still allow the reading of present DVDs, along with the passing to the holographic storage era, the DVD days are over.
So, all in all, this famous "disc format battle" could be won by a surprise competitor. Will Blu-Ray and HD-DVD sell, in these 4 years while the HVD is expected to pass its prototype stage? Hard to tell, since many believe that the DVD is dying, but never surrenders! |

such a format is nice but it will never fly if it doesn't get support from the studios to have their movies released on this hybrid format.
The solution at this stage is to wait it out before making the purchase. One of the formats will eventually vanish and more hybrid players will be made available. |

In 2 or 3 years, china will produce hybrid players for $ 30 or less. |

the price will eventually drop but I doubt it'll ever go that low ... I am sure the HDCP are about 30 dollars or more at least! :p
And if someone manufacturers non HDCP compliant players that will defeat the purpose as HDCP displays will downgrade the resolution ...
when the dvd format came out protection from digital copy wasn't much of a concern just yet ... and licensing fees are really low ...
fyi the HDCP protection has already been cracked, even before it's commercial release but no cracks are easilly findable on the market but things will change

I have a feeling costs are going to be insane. You can't just revolutionize storage without paying for it. We'll see.
Imagine HVD based hard drives... yummy. |

| I have no problem waiting this technology out. There is no way I'd spend $1K for a DVD player, they are gonna have to get the price below $300 before most people would even look at one. |

Well we were supposed to a consumer model of such a technology from Maxell in 2006, but it never happened. They introduced the idea in 2004-2005 with disc capacities at 250GB+, and said recorders would be ready for 2006.
Its a great idea, but this type of storage would only be for the corporate world, as 1tb for video is outlandish. You would need a state of the art computer sitting beside your TV to play, and handle that kind of data rate for movies. Blu-ray and HD-DVD players are already stripped down computers.
I guess with the format wars its going to be a trade off in terms of compression vs resolution. They should be moving towards a standard which allows them to put full uncompressed AVI's on the disc, with PCM audio tracks. But again, the data rates would be just too high. |

Well here it is:
| quote: | InPhase Technologies has begun bulk shipping of its 300GB holographic storage disks and drives, the firm said yesterday. The Tapestry HDS-300R drive costs $18,000, with the 1.5mm-thick platters running to $180 a piece. The firm already claims a series of high profile customers, including Turner Broadcasting, the US Geological Survey, and Lockheed Martin.
InPhase's roadmap sees a series of capacity increases, with disks expanded to 1.6TB in 2010. Data is currently transferred from the platters, which are expected to have a 50-year lifespan, at 20MBps.
InPhase marketing VP Liz Murphy said: "We've also tried to make it as easy to integrate as possible from a software perspective. So it can emulate a DVD, CD-R, magnetic optical disc or tape drive. So software companies don't have to do any major changes to write to it in native mode."
Despite pitching the price point somewhere in the mid to high-end tape drive, InPhase says it is not interested in the backup market and will concentrate on archiving. CEO Nelson Diaz said: "We're not going to play in the back-up market at all."
A re-writeable version of the format is expected in 2008, however. |

| Holographic CD/ DVD/ Whatever media pop up every couple of years. It seems that there are more barriers to making this a viable commercial technology than people assume. Given that I recall reading about this stuff back in 1998... |

Of course you could have read about it in 1998, because they probably announced their initial research back then. Any big technological change is first announced 5-10 years before it even comes to market.
When was the first time we heard of HD dvd or blue ray? The point is, that holographic storage is finally here. |

$180 buys a HDD > 300GB. Acutally, it buys two 320GB HDDs (see newegg), which do not require an up-front investment of $18k for a reader.
But yes, holographic storage is interesting, I am just not going to wet my pants over it just yet. |
