As HD DVD-R is based on the DVD structure, existing DVD-Recordable manufacturing lines can be used to produce HD DVD-R's by utilising the new dye instead. Both Hitachi Maxell and Mitsubishi Kagaku Media/Verbatim have performed trial productions of HD DVD-R discs using their existing DVD recordable production lines and can confirm that these can be used to efficiently mass produce HD DVD-R discs. Commercial productions are expected to begin next Spring, in time for the launch of standalone HD DVD recorders as well as PC HD DVD drives.
The four companies are delighted with their progress and expect the demand for HD DVD to substantially grow once the media and drives are launched. As around 90% of recordable DVDs sold in 2004 were write once media, the Chief Fellow of Toshiba's Digital Media Network Company expects the next generation HD DVD write once media to be just as important.
