BDA: New Blu-ray 128 GB Spec Not Meant For Movies

25 Jun, 2010 By: Chris Tribbey

Blu-ray Disc fans shouldn’t expect an entire TV series on one disc any time soon.

The Blu-ray Disc Association (BDA) approved specifications for a 128 GB, multilayer recordable version of the high-def format June 25, but the organization stressed that the added capacity was unlikely to be used by content owners for commercial releases. The specification, BDXL, allows for four layers to a write-once disc, for up to 128 GB of data, or three layers for 100 GB of data for a rewritable disc.

The BDA said the new Blu-ray specification was likely to be used by broadcasters and medical and document imaging enterprises that could take advantage of the extra storage capacity. Blu-ray consumer video content is currently delivered on 25 GB and 50 GB discs. The BDA said that possible BDXL consumer uses could eventually include the capturing of HD broadcast and satellite programming on capable set-top boxes.

Current Blu-ray players in the market would not be able to handle 128 GB or 100 GB discs, even with a firmware upgrade.

“The BDA worked diligently to create an extension of the Blu-ray Disc format that leverages the physical structure of the design of the disc to create even more storage capacity,” said Victor Matsuda, chairman of the Blu-ray Disc Association Global Promotions Committee. “By using the existing Blu-ray technologies, we have created a long-term and stable solution for archiving large amounts of sensitive data, video and graphic images.

“We expect further growth of the Blu-ray Disc market as the introduction of 100GB/128GB discs will expand the application of Blu-ray Disc technologies.” 

Blu-ray manufacturers can find BDXL licensing information and applications at www.blu-raydisc.info.

In its June 25 announcement, the BDA made no mention of IH-BD, another considered specification that would add a read/write layer to Blu-ray Discs.
