Today鈥檚 DVD discs look puny already. Sony and Pioneer last week demonstrated
the first erasable disc that uses a tightly focused blue laser. The short
wavelength means more information can be packed in. The disc can store 22
gigabytes compared to only 4.7 gigabytes on a DVD, so it can hold 8 hours of
video. The two companies are working with Philips on developing a DVR-Blue
recorder for launch in the next couple of years.
