cdanteek Posted May 29, 2008 Report Share Posted May 29, 2008 article..... One secret sauce is the use of a Rhodamine-type dye in a recording layer. It is excited by laser light and reacts to give off light when excited by another laser at a different wavelength. Such light emission or its absence can be used to indicate binary ones and zeroes. The dye spots are tiny and can exist in 200-250 layers thus providing the 1TB capacity. The use of a single lens to read multiple layers is enabled by having a fluid-filled lens and increasing/reducing the fluid content and thus the lens' profile and its focal length. The I/O rate is said to be around 100MB/sec, five times faster than InPhase's holographic drives. Link to comment Share on other sites More sharing options...

Brendon Posted May 29, 2008 Report Share Posted May 29, 2008 Oh dear. I do hope we're not going to see an endless series of "Rhodamine dye is only good for permantly losing data" posts. Link to comment Share on other sites More sharing options...
Guest ml Posted May 29, 2008 Report Share Posted May 29, 2008 "The process is not reversible and produces write-once-read-many (WORM) media" A new use of a technological term...... WORM! So now we have a good worm that writes mediai and a bad worm (one that infects your computer.) It's not going to be of much use until they find a way to rewrite on the media..... unless of course DVDs reach the 1 TB level. Link to comment Share on other sites More sharing options...
cdanteek Posted May 29, 2008 Author Report Share Posted May 29, 2008 "The process is not reversible and produces write-once-read-many (WORM) media" A new use of a technological term...... WORM! So now we have a good worm that writes mediai and a bad worm (one that infects your computer.) WORM is an inherent property of some data storage media and devices, in which the storage medium is physically incapable of being rewritten. WORM storage media include CD-R and DVD-R. Older punched media such as punched cards and paper tape are WORM because the holes cannot be restored. Electronic circuits such as PROMs are also WORM. It's not going to be of much use until they find a way to rewrite on the media..... unless of course DVDs reach the 1 TB level.

The Highlander Posted May 30, 2008 Report Share Posted May 30, 2008 Brendon' said I do hope we're not going to see an endless series of "Rhodamine dye is only good for permantly losing data" posts. He he he, and as to the Worm comment, I'm going to have to go back to PC acronym school again if they start changing known names of virus to ligit PC hardware names ..

Brendon Posted May 30, 2008 Report Share Posted May 30, 2008 Hey Neil, WORM is an old acronym. Philips exhibited a WORM drive when you were still wearing short trousers. http://www.scantastik.com/data-storage/pla...dfs/worm_wp.pdf Regards, Brendon Link to comment Share on other sites More sharing options...
