320 GB Write Once Optical Disc by TDK

TDK Corp. developed a write-once optical disc with an impressive capacity of 320 Gbytes. This goes well above the capacity of a Blu-ray disc that has a total of 25 Gbytes per layer. The means of writing and reading data from this optical disc that requires a blue-violet semiconductor laser with an oscillation wavelength of 405nm and an objective lens with a numerical aperture (NA) of 0.85, that are currently used for the Blu-ray discs. TDK recording format in 2006 that had six layers, each of 33.3 Gbytes in capacity, adding up to the 200 Gbytes total capacity. As the number of recordable layers increase, the signals of each layer get weaker, requiring improvement in the transmittance of the layers. The transmittance of the outermost layer, that needs to be the highest, now reaches more than 90%, while the 2006 prototype barely had 80% to 90%. The layer architecture of the new disc comes as – a cover layer and a hard coat layer are formed on recording layer (the innermost L0 layer to the outermost L9 layer), while the L0 layer features a Si-Cu alloy, which is inorganic.

BDR 205 Blu ray Disc Writer

Pioneer Electronics, one of the world’s leading vendors of consumer electronics and a member of the Blu-ray Disc Association, has just announced the debut of its new BDR-205 Blu-ray Disc computer writer. “The BDR-205 drive represents our ongoing efforts to combine Pioneer’s engineering expertise with advanced technologies, and our next generation Blu-ray Disc writer is a great example of our no-compromise approach to optical disc product development,” said Steve Cohn, director of optical disc sales for Pioneer Electronics (USA) Inc. “We are bringing to market the fastest Blu-ray Disc writer to date, and it is just one of the many ’firsts’ that have come to define Pioneer’s 30-year heritage in optical disc innovation and leadership.” New Blu-ray Disc writer, it can reach write speeds of up to 12x, using the Panasonic and Sony 6x BD-R media, for single-layer and dual-layer drives. This should enable data to be written faster on the high-capacity optical media, providing users with a faster way to store as much as 50GB of digital content. In addition, the new drive also comes with Pioneer’s Low Vibration Mechanism Design. It will be out on the 1st quarter of 2010 and costs US$249.
