Can a 51Gb HD DVD beat Blu-ray at 50Gb?
itwire: Despite reports that Toshiba’s new 51Gb HD DVD has been submitted for approval, this hasn’t yet happened – but even if it was, will it make any difference?
In the war for technological supremacy, companies like to boast how their devices are better than the competition. In the world of LCD and plasma TVs, this means that the competition makes a screen 1-inch larger, which is then bettered by another inch.
Now in the world of next-generation, high-definition discs, the same looks set to happen again, with Toshiba having created a prototype 3-layer HD DVD disc, with each layer now holding 17Gb instead of 15Gb, for a total size of 51Gb, or 1Gb larger than Blu-ray’s 50Gb discs.
While plenty of sites have reported that the new disc had been submitted for approval, PC World has quoted Toshiba as saying that it isn’t so, with Toshiba spokesperson Junk Furuta saying that: “We’re puzzled ourself by where these reports came from.”
Toshiba have a couple of problems in getting this disc not only to market as a successful competitor to Blu-ray, but as the format that consumers prefer. The first is that existing HD DVD players probably won’t be compatible with the new discs, meaning new players will need to be purchased. If existing players can be firmware upgraded, all good and well, but normally, a new disc format needs a new reader.
