[X-Newbies] Blu-ray discs

[Verduron]

TDK has developed a prototype Blu-ray Disc that can store twice as  
much data, and record it at twice the speed, as existing Blu-ray  
Discs. The disc, unveiled at a TDK exhibition in Tokyo this week, can  
record data at 72Mbps, double the 36Mbps transfer rate for current  
Blu-ray Discs. "TDK increased the write speed by using a more  
powerful laser and making some changes to the material of the disc's  
recording layer," said Nobuyuki Koike a spokesman for TDK. "The first  
generation of Blu-ray discs can already record data faster than it is  
transmitted in high-definition TV broadcasts, so the faster recording  
speed isn't needed there. But it will be advantageous when content is  
copied from a hard-disk drive to an optical disc for back-up or  
archiving," said Koike.
