Fuji Photo Film Co., Ltd. announced its development of a blue-violet laser write-once optical disc that uses an organic dye coating technology "ideally suited to mass production."
The new disc is produced using a spin-coating technology to apply a newly developed organic dye to an optimized substrate. The organic dye is then covered with a 0.1mm cover layer. Using a recording/playback device with a 405nm wavelength blue-violet laser and an objective lens with a numerical aperture (NA) of 0.85, the discs offer storage capacities of up to 23.3GB.
The company said the discs can be manufactured using the existing equipment infrastructure for dye-coated CD-Rs and DVD-Rs.
Fuji said it will work to incorporate its technology into the standards of the Blu-ray consortium, whose discs employ the same laser, numerical aperture and "cover layer" construction, but claim a capacity of 27GB. Fuji also stated the technology would be compatible with the rival next-generation DVD proposal from Toshiba and NEC.
