But to use it, you’re going to need a new player...
The Blu-ray Disc Association announced that two new specifications will be unleashed within the next few months. IH-BD is the first, and it probably won’t matter for you. It’s a hybrid that allows part of the disc to be read-only, while allowing the other part to be written. BDXL on the other hand, has immediate and obvious uses.
Initially, BDXL, which allows write-once discs to hit 128GB in size, will be marketed and sold for commercial applications. Broadcasters will be among the first to get these, along with medical and document imaging businesses. But according to the press release, “A consumer version of BDXL is also expected, particularly in those regions where BD recorders have achieved broad consumer acceptance.”
BDXL players can be made backwards compatible with Blu-ray discs, but it doesn’t work the other way around. Larger capacity discs seem cool, but you’ll need to pick up a new player in order to use them.
