Sony also confirmed that it plans to start shipping 50GB dual layer
rewritable BD media later this year.
“The arrival of 50GB Blu-ray Disc media is an important milestone in the
evolution of this new format,” said Sumant Sharma, Product Manager, Recording
Media and Energy Products, Consumer Audio Visual/Information Technology Group,
Sony of Canada Ltd. “The capacity represents more than four hours of
High-Definition-quality video, at a 24 Mbps (megabits per second) transfer
rate, allowing users to take full advantage of Sony’s Blu-ray Disc burners and
VAIO desktop and notebook personal computers.”

Mr. Sharma said that Sony’s AccuCORE technology has been re-engineered
for Blu-ray Disc media, with its major benefits including scratch guard,
archival reliability to prevent data/image corruption and deterioration,
stable writing that reduces fluctuation as the disc spins, and temperature
durability to prevent warping during severe changes in temperature and
Sony’s 50GB BNR-50AH dual layer recordable disc has a manufacturer’s
suggested retail price (MSRP) of $49.99.
