Sony has revealed a new line of high-end, high-def video cameras that can use blue laser optical media. Sony's new XDCam HD series of video cameras can record 1080i high-definition video with variable frame rates and can use Sony's new blue laser Professional Disc media. The blue laser Professional Disc will be one of the first blue laser optical media formats available on the market. Don't expect to use them before Blu-ray or HD-DVD, though; the blue laser Professional Disc-compatible camcorders will cost between $15,000 and $27,000. Both the blue laser Professional Discs and the XDCam HD camcorders will ship in June. Each blue laser Professional Disc will cost about $30 and will store 23.3GB of information.
