Pioneer And Mitsubishi Chemical Develop Organic Dye For Blu-ray Discs


Recommended Posts



Pioneer and Mitsubishi Chemical announced today that they have developed a new type of BD-R disc that uses organic dye in the recording layer. This new media corresponds to the "Low to High" (LTH) recording system which is included in the Blu-ray Disc Recordable Format Ver 1.2 specifications. Here's part of Pioneer's press release, translated from Japanese:


Both corporations advanced the cooperation development of the pigment type blue ray postscript type disk from 2004. This time, the Mitsubishi chemical media took charge as for the pioneer of the appraisal of the trial manufacture disk and the verification from viewpoint of compatibility of drive and of the further improvement and disk trial manufacture of the organic pigment record material, the design of the disk structure with simulation took charge. It succeeded in the development of 2x fast record organic pigment system BD-R by fusing the technology these both.


In addition both corporations, ever since the announcement of cooperation development 2005, advanced the standardization propulsion activity of the organic pigment type record media, but this spring, the recording type which corresponds to organic pigment system BD-R (Low to High system) was adopted for Blu-ray Disc Recordable Format Ver.1.2.

Pioneer and Mitsubishi Chemical claim that this dye will lower production costs as companies using it will be able to produce discs using modified CD-R and DVD-R manufacturing equipment. The big catch here is that discs using the LTH system will not be compatible with existing Blu-ray writers. While Pioneer is working on a new drive that can write to these discs, it is unknown whether support can be added to older drives via a firmware update.

Organic dye ... :blink:


What happens if it gets a virus ... :huh:



It can't, Lynn, because a DVD is hermetically sealed at the edges.


However if it wasn't, you'd permantly lose all your data, I guess. :)


Are you still rooting for blu-ray?
