100GB Blu-ray discs coming soon ... to Japan

Remember when the 1.44MB of a floppy disk seemed like all you'd ever need? Pah! Sharp and TDK have announced that they plan of releasing 100GB BDXL Blu-ray discs.

Remember when the 1.44MB of a floppy disk seemed like all you'd ever need? Pah! Sharp and TDK have announced that they plan of releasing 100GB BDXL Blu-ray discs.

The Blu-ray Disc Association finalized the new BDXL specification in June, and it's not taken manufacturers long to start making discs.  Sharp announced plans to release 100GB discs in Japan at the end of July, while TDK's offerings will hit shelves early September.

The BDXL standard offers 33.4GB per layer of storage on four layers (compared to the 25GB per layer on a maximum of two layers for the current standard), although it seems that no one is currently going for 4 layer discs, instead being content with making use of three layers.

The bad news - while BDXL players are backward compatible with Blu-ray, older players won't work.

Oh, and these discs, along with the required players, are only available in Japan. There are no plans to market them worldwide ... yet.
