Sony 50GB Dual Layer Blu-ray Discs Hit U.S.

Sony Electronics on Wednesday started shipping its 50GB dual-layer Blu-ray Discs that feature its AccuCORE technology, though the discs can be recorded onto only once, according to an Aug. 16 Sony press release on PRNewswire.com.

Sony said it will ship rewritable, dual-layer 50GB discs by the end of the year.

Mike Lucas, director of marketing with Sony Electronics’ Media and Applications Solutions Division, said, “The arrival of 50GB Blu-ray Disc media is an important step in the evolution of this new format.”

Lucas also said the 50GB dual-layer discs can record up to four hours of HD-quality video content at a transfer rate of 24Mbps.
