Toshiba evidently dont like the fact that their HD-DVD standard isnt up to par with Blu-ray as far as capacity goes (15GB vs 25GB per layer), which when you're talking dual-layer discs allows for an even bigger lead against them. Yet they've still managed to work a way around it and in fact beat out the Blu ray standard!

How so? Well for a start they've worked out how to squeeze in another 2GB per layer (17GB) then they've gone and developed a triple-layer HD disc bringing the total capacity to 51GB, a mere 1GB more than dual layer Bluray discs. Sounds like there's a real war in place here, whats next? Quad layer Blu-ray?

More details at The Dailytech.

HD DVD's dual-layer 30GB and Blu-ray's dual-layer 50GB media is enough space to store crystal-clear 1080p video and uncompressed audio for today's movies, but media manufacturers are continuously looking for ways to increase capacity. Toshiba Corporation quietly announced on the first day of CES that the company has developed a triple-layer HD DVD-ROM (read only) disc with a capacity of 51 gigabytes.

HD DVD discs hold 15GB per layer. In order to reach a dual-layer Blu-ray Disc-besting capacity, an extra 2GB per layer was squeezed in, for a total of 51GB. Toshiba states that continued improvement in disc mastering technology has achieved further minimization in the recording pit, allowing for the boost in capacity to 17GB in single layer and a full 51GB on a single-sided triple-layer disc.
