On the heels of the news of Toshiba's proposed double-standard disk comes word that Warner Brothers engineers have applied for a patent on a triple-standard disk. The new disk would offer HD-DVD and Blu-Ray on one side and standard DVD on the other. From the article: "Warner's plan is to create a disk with a Blu-ray top layer that works like a two-way mirror. This should reflect just enough blue light for a Blu-ray player to read it okay. But it should also let enough light through for HD-DVD players to ignore the Blu-ray recording and find a second HD-DVD layer beneath." See the patent application, filed last month.
