Japanese company Optware will commercialize an optical disc that can store more than 1 terabyte of data, and an associated disc player, later this year, the company said earlier this week.
The disc and player are based on a 5-inch optical disc like existing CDs and DVDs, but the new disc will be able to store about 120 DVD-format movies, according to Atsushi Machida, a spokesman for Optware.
The high capacity--around 20 times the storage available on existing discs--and a data transfer speed of 1 gigabit per second have been achieved by using digital volume holography read/write technology, developed under the Defense Advanced Research Project Agency (DARPA) in the United States, according to Optware's statement.
