The Blu-ray Disc Association (BDA) confirmed that existing Blu-ray players will not be compatible with 100GB or 200GB BD media:
Even though Blu-ray disc technology allows creating multi-layer high-capacity media that can store hundreds of gigabytes of data, the Blu-ray disc Association (BDA) claims officially that existing Blu-ray disc players will not be compatible with 100GB or 200GB BD media. Nevertheless, BDA claims that 50GB will be enough for movies for many years to come.
“I think there will be applications for larger capacity recordable discs, but it would be difficult for [discs larger than 50GB] to achieve compatibility with the installed base of players. This is because player manufacturers design players to meet published specifications that define maximum media capacity, which in the case of Blu-ray Disc, is 50GB on two-layer media,” said Andy Parsons, senior vice president of corporate communications and new product planning for Pioneer and the chairman BDA’s promotion committee in the U.S., in an interview with Home Media Magazine.
