Photos: HD DVD and Blu-ray battle in Tokyo

The battle over who will rule the next DVD era is a main attraction at Ceatec Japan 2005, the information-technology and electronics show that opened Oct. 4 in Tokyo. Here, a Toshiba employee shows off one of the contending technologies: a player geared for the HD DVD format and a 30GB double-layer disk.

HD DVD's adversary is the Blu-ray format. In this photo, a Sony employee at the Ceatec Japan 2005 show displays a prototype Blu-ray player and Sony's BD-ROM disks. Disc capacities for the Blu-ray format are 25GB and 50GB.
