Iomega Patents 850GB DVD Nano-Technology

Mike writes "US Patent & Trademark Office recently issued a patent to Iomega Corp. for its work with nano-technology and optical data storage. New technology, called Articulated Optical - DVD will allow 40-100 times more data (upto 850 Gb) to be stored on a DVD with data transfer rates 5-30 times faster than today's DVDs, and at similarly low costs. AO - DVD is a novel technique of encoding data on the surface of a DVD by using reflective nano-structures to encode data in a highly multi-level format."

I call bullshit

[autopr0n]

I once sold a backup solution to a company who decided to go with DVD's rather than tape for the cost of the media alone. Three months later someone moving the dvd platter dropped it on the way to the vault...a Company that had been in business 20 years was out of business because of one mistake and cheap media.

If it was on the way to the vault, why didn't they just do anther backup? Why didn't they just restore from an older backup?

Also, DVD's do have protection against scratches, the layer of accrylic covering the data layer. If that part gets scratched, it dosn't really matter, because the laser dosn't focus on that part. Scraches and imperfections 'dissapear' from the POV of the DVD player.

They also put a lot of redundant data on the disk, so that if some of the bits are lost, the disk is still readable.

you confused CD-R with DVD-R

The NIST publication "Care and Handling of CDs and DVDs - A Guide for Librarians and Archivists" says CD-R has the soft acrylic layer under the label, data layer, and polycarbonate layer and DVDs have a polycarbonate layer on both sides with the data layer sandwiched inbetween.

This is why CD-Rs are much more fragile than DVD-Rs.
