Try scratching this DVD

Researchers at electronics giant TDK have developed a tough new coating that promises to make scratched DVDs a thing of the past and that will help usher in an emerging data storage format with 10 times the capacity of the current DVD standard.

In a test conducted by CNET News.com, a DVD treated with TDK's coating survived a determined attack with a screwdriver and a Sharpie permanent marker with no effect on playability--a remarkable feat considering how easily standard DVDs can be damaged, for example, by children.

"Wow, every family with a young boy could really use that," quipped Elizabeth Berry, a Berkeley, Calif., resident and one-time Netflix DVD-by-mail subscriber, when told of the scratch-resistant coating. "My 3-year-old must have destroyed half my DVD collection." Already one of the most popular technologies in history, the DVD is poised for further greatness as companies tinker with improvements such as better durability and increased storage.
