50GB doesn't seem to be enough for optical media so the Blu-ray Disc Association (BDA) has stepped up and introduced two new, high-capacity specifications based on the Blu-ray technology - BDXL and IH-BD. The BDXL specs will enable the release of write-once discs with up to four layers that can store up to 100GB and 128GB of data, and rewritable discs with up to 100GB of space.
The Intra-Hybrid Blu-ray Disc (IH-BD) incorporates a 25GB BD-ROM layer and a 25GB BD-RE layer so the user can view and not overwrite the data put on the former, but also write on the latter.
"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 BDXL and IH-BD specifications are set to be made available in the next few months.
