According to the Blu-ray Disc Association (BDA, a group of companies responsible for the development of standards, promotion and development of Blu-ray disc), Blu-Ray discs to 100GB and 200GB are not compatible with existing Blu-Ray drives. So, despite the fact that some manufacturers, including Sharp and TDK, have announced the release of multi-layer discs with high recording density, which can potentially store hundreds of gigabytes of information, consumers may not be able to take advantage of their opportunities as well as modern drives can not handle drives larger than 50GB.

"Manufacturers create a drive devices for existing specifications that define the maximum disk capacity, which is the case with Blu-Ray is 50GB at double layer drive", ─ says Andy Parsons (Andy Parsons), a senior vice president at Pioneer, in an interview with Home Media Magazine. ─ "I think that for recordable discs are high capacity applications, but drives larger than 50GB, it would be difficult to achieve compatibility with existing drives.

Parsons believes that Blu-ray Disc high-capacity must be writable media. He said that future Blu-Ray drives will support Blu-Ray disks of high capacity and their development will have a lot in common with the development of magnetic media such as VHS, when the carrier is gradually increased in volume, and new tapes are incompatible with the old VCRs.
