A New DVD Format WarWritten by Roger Faraway
Continued from page 1
are two competing high capacity DVD technologies, HD-DVD (High Definition DVD) and Blu-Ray. HD-DVD works by using multiple layers on a single disk, and its main advantage is its low production costs. Blu-Ray is technically superior – it uses blue laser light instead of red light used by existing players. This blue light has a smaller wavelength, and so pits that it creates on surface of DVD to encode data, are smaller. Smaller pits means more pits in same space, which means higher capacity. Blu-Ray can store more information than HD-DVD, but presently is more expensive to implement. When Blu-Ray is combined with multi-layering technology behind competing format, it will see capacities rise to as much as 200 Gigabytes. Existing DVDs hold only 4.7 Gigabytes.The battle will most likely be won by format that gets most support from big Hollywood studios – nobody is going to opt for a DVD standard with a small catalogue of titles. With Blu-Ray being backed by likes of Hitachi, HP, and Sony (who own MGM studios), it would appear to have edge. Hollywood however, is remaining non-committal, afraid of backing a losing horse. For now then at least, formats are caught in something of a chicken-and-egg situation. As has been case so many times in past, only time will tell which format will come out on top.
