Blu-ray doubles storage capacity

Posted by Emma Woollacott

The Blu-ray Disc Association (BDA) has announced a new high-capacity format, more than doubling the amount of storage capacity.

The BDXL specification, which is targeted primarily at commercial segments such as broadcasting, medical and document imaging archiving applications, ups the storage to 128GB on write-once disks and 100GB on rewritable disks. A consumer version is also expected.

The group's managed it by incorporating three to four recordable layers, compared to the current two. But because this requires a more powerful laser, the new format won't be compatible with current hardware.

"Professional industries have expressed a desire to find optical disc solutions that enable them to transition away from magnetic media for their archiving needs," says 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."

Also new is the Intra-Hybrid Blu-ray Disc (IH-BD). This incorporates a single BD-ROM layer and a single BD-RE layer, each with 25GB of storage.

It enables users to view, but not overwrite, published data while letting them include relevant data on the same physical disc, says the Association.
