Page 1 of Will this new technology spell the slow demise of Blu-Ray??? well it be a few years off :)

Just reading on Sky News Website this morning about some scientists in Australia who have found a process to expand the humble dvd`s potential to store over 2000 films worth of data on one disc. I thought it was interesting reading and thought I would share it with you all to have a read. Quite interesting.

I knew I should have waited to put all my dvd`s to my media server ;)

Technology that could see a single DVD hold more than 2000 films has been unveiled by scientists.

Thousands of films on just one CD - potentially


So-called five dimension data storage uses nanotechnology and can boost the storage potential of standard format DVDs by almost 10,000 times.

The latest development has come from a team of researchers from the Swinburne University of Technology in Australia.

"We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc," the research leader, Min Gu, told news.com.au.

Currently, DVDs have three data storage dimensions.

However, using nanorods made of gold, the Melbourne-based team were able to add two more - one based on the colour spectrum and the other on polarisation.

The breakthrough has meant it is now possible to record information in a range of different wavelengths at the same place on the disc.

Current DVDs record in a single wavelength, using a laser.


The relevant process is called polarisation, where nanoparticles react to light depending on their shape.

And the introduction of the new gold nanorods has meant this process can now be manipulated.

"The polarisation can be rotated 360 degrees," explained the co-author of the research, James Chon.

"We were, for example, able to record at zero degree polarisation.

"Then, on top of that, we are able to record another layer of information at 90 degrees polarisation, without them interfering with each other."

The team are still working on reducing the speed at which the discs can be written and commercial production is at least five years away.

Nonetheless, they have signed an agreement with Korea-based electronics giant Samsung.

The news comes soon after one of the largest US-based technology companies, General Electric, said it had developed a holographic disc capable of storing the equivalent of 100 standard DVDs.

I can`t see the Studios selling commercial DVDs with more than one film on each disc...

I mean today they don`t even fill some discs up so they can make it a 2 Disc Set and charge you a little extra.

i think the 2000 films bit was a guide as a simple this is how much the disc can hold data wise..... not as in multiple films on a disc, the article should have made it a bit clearer. Its about the data storage.

Typical unclear SkyNews

They could put a whole TV Series on one disk, or all the Bond (for instance) Movies. Less packaging, more profit & more room for our bulging shelves.

Sorry to ask again but your sig is taking up over half my screen and we don`t have the hardware budget for a new one at the moment so would you please reduce it significantly?

Thanks in advance.

This should be better.

Blu ray has more information than a DVD disc, yet they still have the same amount of discs in a TV box set.

You would think that because it holds so much information, they would be able to halve the amount discs needed.

But then as you probably know, Blu-ray videos are a much higher bitrate and thus bigger filesize as a result. Are they using Blu-ray disc space to its full potential yet?

Would a box set be a box set with just one disc?



WELCOME TO KINKY CLUB.

Would a box set be a box set with just one disc?

I think so. You could put a bigger booklet explaining about the movies etc. You could also put say the bond movies on 3 or 4 discs. Still saving space. You could put the Connery ones on one & so on. It just needs a little imagination. I take your point though.
