The first holographic storage systems, storing up to 300GB on a single disc, will go on sale towards the end of 2006.
InPhase Technologies and Hitachi are jointly developing the technology, which uses laser light interference to store data in a light-sensitive crystal material.

The technique could be developed to store up to 1.6 Terabytes on each disc - more than 300 times the capacity of a conventional DVD - and offer read and write speeds of up to 120Mbits/sec.

'Unlike other technologies, that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light,' Liz Murphy, of InPhase Technologies, told New Scientist. 'This enables transfer rates significantly higher than current optical storage devices.'

The high transfer speed enables the playback of broadcast-quality HDTV content, of which 26 hours can be stored on a single disc.

'We believe the capacity and data rates of holographic storage will be critical to achieving the breakthrough improvements in work flow and cost reduction that the broadcast industry is seeking,' said Nelson Diaz, InPhase's CEO.

Holographic storage works by splitting light from a single laser beam into two: the signal beam to carry the data and the reference beam. The hologram is formed where these two beams intersect causing a chemical reaction in the recording medium. By varying the reference beam angle, wavelength, or media position many different holograms can be recorded in the same volume of material.

300GIG :o

This is incredible, surely Hdisks will need to compete with this, and increase their capacity and reduce the cost.

Yeah, I agree. Although, I'll be surprised if there isn't a way to utilise a similar technology for h.disks.

A while ago it used to be 1Gig = £1 GBP on average. Now the trend seems to be 2Gigs = £1 GBP!

I do think prices will fall, especially that Win Vista is around the corner requiring insane amount of disk space and ram for that matter too.

Yeah, the 400gig external hdd I just bought worked out at roughly 50p per gig.

I wish Flash drives/USB sticks were this cheap... i really want a large capacity one but the prices for them are very expensive at the moment.

Yeah, I've always wanted one of those little things. Well, now I just use my 20gig ipod.

How big can flash memory go though?... On a chip(s), rather than hard drive. I'm guessing it can only go up to a few gig as I've never seen anything bigger, mp3 players included (excluding hdd ones of course).

I've seen normal retail USB Flash memory go as high as 4gigs. But usually comes with a very high price tag. I believe you can get even higher as I havent been following them up recently.
