Holographic Versitile Disc (HVD)

Has anybody else heard about these things? I find this part particularly intriguing:
Holographic recording technology records data on discs in the form of laser interference fringes, enabling existing discs the same size as today's DVDs to store as much as one terabyte of data (200 times the capacity of a single layer DVD), with a transfer speed of one gigabyte per second (40 times the speed of DVD).

Is it just me, or does that not make you wanna go :D ?

A newly developed computer storage medium released today promises to offer more than a terabyte of storage on a single disc.

Dubbed holographic storage, the technique allows greatly increased data storage and was first proposed in the 1960s.

Now US company InPhase Technologies claims to have built the first media capable of storing data holographically, and is shipping the Tapestry HDS5000 discs to device developers for testing.

optware would seem to have made more contributions to HVD's than inphase has, as evidenced by the fact that they - and not inphase - are quoted in this article about HVD's:

the other possible successor to blu-ray / hd-dvd's are optical discs with uv lasers, as described here:

here's a wikipedia article (complete with pictures) on hvd:

ok, lets see -- watch a movie on a medium the size of a nickel. And i wonder how long the burn speed is?

You could end up fitting your entire music, movie, anime, tv show, porn, book collection in your wallet.

oh the possibilities...

The HVD also has a transfer rate of 1 Gbit/s.


About the same I guess. I'll only take up to 4.7 secs for one whole movie.

So you could fit 213 full DVD movies on that very one disk and it'll only take 1001 seconds (about 16 minutes) to burn them all.

InPhase has announced plans to release HVDs. They expect the first batch to be out by 2006 and to have 200gb space and a 20mb transfer rate:

1TB discs are due out in 2009:

Apparently InPhase and OptWare are using two different techniques to create HVDs.

An InPhase Tapestry holographic disk will hold 60 times as much data as a DVD and write data as much as 10 times faster, the company says.

and...

Collinear holography, a second approach to holographic storage, also is expected to result in DVD-sized terabyte-class storage devices. The technology, provided by Japanese vendor Optware, is as much as 40 times faster than traditional DVD, the company says.

InPhase is apparently shipping their stuff, now:

At $180 / disc and $18,000 / player, however, I think they may have a tough time finding buyers.

Moderately slow and insanely pricey compared to a hard drive. But I do like the life expectancy. I assume that's the reason why they think they will be major players in the archive business?

Another company that thinks they have the successor to the successor of DVDs:
