100 gigs in your pant pocket? You heard right..Taiwanese researchers have developed a DVD-compatible optical disk with a 100 gig capacity. TAIPEI, Taiwan â€” Forget about 100-gigabyte portable hard drives â€” too bulky. A physics professor at a leading Taiwanese university has led a group of researchers in developing a recordable optical disk capable of packing in 100 Gbytes of data and slipping into a pants pocket. That's about 30,000 of your favorite songs, or enough tunes to toe-tap to for a few months. The disk is compatible with today's CD and DVD technology, running off the same red laser pick-up heads used in a typical disk player. "That's the most attractive part of this technology," said Wang Shyh-Yeu, director of research at Ritek Corp., a disk maker that co-funded the study and will likely commercialize the disk in 2005 or 2006.
