TOKYO, August 29 -- Toshiba Corp. and NEC Corp. have proposed to the DVD Forum a next-generation, high-capacity, blue-laser DVD format that will allow manufacturers to continue to use existing DVD plant and equipment. The format covers both read-only discs, which are used to distribute high-definition movies, and read-and-write discs. The format uses a short-wavelength blue laser and the same disc technology used in current DVDs -- back-to-back bonding of two 0.6-mm-thick, 120-mm discs. This would increase the capacity of read-only discs to 15 GB for a single-sided, single-layer disc, and to...Read full articleRelated content from Photonics MediaArticlesCepton Lidar to Feature in Highway Tolling SystemsCepton has won a multimillion-dollar sales contract from one of the largest highway tolling system operators in the U.S., the lidar technology company said.
