Looks like at worst we will just have to buy new DVD players in the next year or so to get the new disks to work:
A dozen companies, headed by Sony Corp., are pushing a disc called the Blu-ray.
The new discs, which look much like DVDs, would be read by players with newly developed blue lasers, which can pick out finer detail than the red lasers used to play DVDs and CDs. This lets the new discs store three to five times as much data as a DVD, enough for high-definition movies with surround sound.
Manufacturers from both groups plan to also build red lasers into their new players, allowing them to read current DVDs.
The Blu-ray disc has the most storage capacity, up to 50 gigabytes. However, it achieves that capacity by using a structure quite different from DVDs. This means that the companies that make prerecorded DVDs would have to invest in new equipment, which is sure to give Hollywood pause as it ponders which format to back.
The Blu-ray does have the widest support among electronics manufacturers, counting not only most of the big Japanese names but also Dell Inc. and Hewlett-Packard Co. in its consortium
