Toshiba announced at the CES that they've made a triple-stacked HD-DVD read-only disc that can hold more ones and zeros than a standard Blu-Ray disc --51 gigabytes. That's a lot of 1080p hi-def goodness:
Ritek said not so fast. We can stack up to ten, and do it in both Blu-Ray and HD-DVD formats. That's up to 250 Gigabytes on one disk. Whoa. There's a problem, of course. Nothing can read them yet. You can read about it not reading it here.
