Blu-ray Discs Expanded to 128GB
The capacity of the Blu-ray disc has been expanded yet again, but this time it has resulted in a new sub-format: BDXL. The new format can store up to 128GB (write-once) or 100GB (rewritable), more than doubling the capacity of the dual-layer BD, disc which can hold up to 50GB of data. Unfortunately, the PlayStation 3 will not be compatible with the new format, even with a firmware update.
Engadget report that the new discs will require 3-4 layers per disc, requiring a more powerful laser to read and write data. The BDXL format is currently targeted at commercial segments so don’t expect a update to the PS3 any time soon (maybe PS4 though…).
Hit the jump for the official press release.
Official Press Release:
LOS ANGELES –(Business Wire)– Apr 03, 2010 The Blu-ray Disc Association (BDA) today announced two new media specifications that use Blu-ray Disc technology to provide targeted functionality for commercial and consumer applications. The specifications for BDXL™ (High Capacity Recordable and Rewritable discs) and IH-BD (Intra-Hybrid discs) are expected in the next few months.
The BDXL specification, which is targeted primarily at commercial segments such as broadcasting, medical and document imaging enterprises with significant archiving needs, will provide customers with write-once options on 100GB and 128GB capacity discs and rewritable capability on 100GB discs. The discs reach these capacities by incorporating three to four recordable layers. A consumer version of BDXL is also expected, particularly in those regions where BD recorders have achieved broad consumer acceptance.
“Professional industries have expressed a desire to find optical disc solutions that enable them to transition away from magnetic media for their archiving needs,” said Victor Matsuda, Blu-ray Disc Association Global Promotions Committee chair. “Leveraging Blu-ray Disc to meet this need provides professional enterprises with a compact, stable and long term solution for archiving large amounts of sensitive data, video and graphic images using a proven and widely accepted optical technology.”
The Intra-Hybrid Blu-ray Disc (IH-BD) incorporates a single BD-ROM layer and a single BD-RE layer so as to enable the user to view, but not overwrite, critical published data while providing the flexibility to include relevant personal data on the same physical disc. This allows for consumer specific applications where combining published content with related user data on a convenient, single volume is desirable. Both the ROM and the RE layers on IH-BD discs provide 25GB of capacity.
Because both BDXL and IH-BD are specially designed formats with specific market segments in mind, newly-designed hardware is required to play back or record BDXL or IH-BD media. However, because the new media specifications are extensions of current Blu-ray Disc technology, future BDXL and IH-BD devices can be designed to support existing 25GB and 50GB Blu-ray Discs.
