DVD-14 is starting to make some noise with new releases from MGM this fall. DVD-14, which is currently manufactured in the United States exclusively by WEA Advanced Media Operations (WAMO), is basically a DVD-9 bonded to a DVD-5. By eliminating the need for two discs, the format can theoretically save content providers money, and, according to Pierre Loubet, vice president of sales for advanced media at WAMO, is a fairly straightforward product to make. Replicators experienced in DVD-9 production should have no problem replicating DVD-14s with very good production yields.
Interestingly enough, the DVD-14 format is also available in an 80mm disc size (the size that Nintendo is using for the soon-to-be-released GameCube). While not quite 14GB (The 80mm disc offers about 2.8GB of storage per layer), the option exists nonetheless.
