Functional dye from Clariant is major element in the next generation of DVDs
In a joint project, Clariant (Switzerland) and Toshiba Corporation (Japan) achieved a breakthrough in the development of the new generation of DVDs: high-density, recordable-once dual-layer HD DVD-Rs (High- Definition recordable DVDs) based on organic dyes, with a storage capacity of 30GB.
Based on their knowledge in single-layer recording HD DVD-R organic dye technology, Clariant and Toshiba developed highly advanced functional organic dyes for both recording layers L0 and L1 that are required in dual- layer disks and significantly increase the disk storage capacity for this new disk type. The dyes offer very high reflectivity, good transmittance, high thermal conductivity, as well as the high sensitivity required for this technology. HD DVD-R DL has already been discussed in the DVD Forum; it is expected that the final specification will be released this year. Clariant will introduce the new dyes for HD DVD-R in the Optofast® range and already started to promote them among disk manufacturers all over the world.
