Guess what? Another kind of super capacity media has been announced - and this time it's an Australian invention. The claim is that the capacity will be enough for 2000 DVDs. Awesome news. It's touted to be going into production in the next five years so it's going to be another wait and see kind of thing. 

This new product uses nano technology with data written in various polarisations. In other words, when the read laser is polarised at zero degrees rotation, there is one batch of data visible. Another batch at ninety degree and so forth. To explain it as simply as I can, it's vaguely similar to the old quadrature ampliteude modulation (QAM) encoding used in modems to achieve v32bis and Trailbalzer speeds, except this is being achieved in an optical environment, in three dimensions, plus altered optical dimensions. Pretty neat, eh?

It's really funny. When you think about duplicating discs it's just a case of getting some copies.

Kind of like going to a photocopy shop and paying for some dude to press the button, or heck - even pressing the button yourself. But as you know, copies can be pretty different in quality. Go to the Kwiki-mart with the old clapped out photocopier and you're probably going to get a pretty disastrous result. Go to a proper copy or digital print shop and it's likely you're going to get a pretty decent copy - maybe even better than you can plainly see with your eyes. Chances are before you bet your money and reputation on getting copies this way, you're going to think it through.

It's the same for CD and DVD duplication.

Everyone 'in the know' in the optical media business as a savvy customer or as a wise insider knows Taiyo Yuden and the quality and value it represents. Their media, both premium and OEM grade offer superlative performance and stability in diverse conditions. 

Late in September 2008, Taiyo Yuden acquired 65% of JVC's recording business. The nett effect of this is that the joined companies' recordable and recording business will produce a giant with incredible commercial performance in the mass-market side of the business as well as the professional media supply market. http://www.yuden.co.jp/us/release/pdf/pdf_100.pdf

And in the news today... 500 Gb holographic optical media.

Yes, that means 100 DVDs on one disc. Blu-Ray? Hmmm - merely one tenth of that capacity and for the most part it still isn't being fully utilised by those who developed it and those who use it as a publishing medium. Then again, that was the situation when DVD first came to the fore. 

This concept has been spoken of for a very long time. In this case, GE is the one who has visibly touted it on the world's stage.Their intent according to the article (link below) is to have media which plays in a device not unlike a conventional CD/DVD/Blu-Ray playback unit.
