Toshiba has announced that it has perfected the manufacture of double layered 30GB HD-DVD-R discs, doubling the previous capacity.
The new design was approved by the DVD Forum's Steering Committee on 14 September, and the discs will be available in the spring of next year. It allows for 15GB of data to be stored on each layer on the disc.
Toshiba's move is important because capacity is one of the chief advantages of the rival Blu-Ray system. However, there will be no Blu-Ray DVD-R specification until at least October.
The new technique uses a specially developed organic dye which penetrates the DVD substrate in a similar way to traditional DVDs. Toshiba believes that the new technique can be built into current manufacturing systems at little extra cost.

Do you agree?
uhhhhh
according to blu-ray.com a single layer Blu-ray disc can already fit 27 Gigs, and a dual layer disc can fit up to 54 gigs. So I don't see how 15 gigs per layer is better.

Maybe 2 differnet markets?
maybe there is two different markets? One is for computer data storage and retrieval and the other is for a domestic recording/replay medium for high definition displays. Market forces will tend to mitigate against two different standards, (ie cost/ manufacture of machinery for production), but the two aims are not necessarily contradictary. Purely on the basis of data capacity one may be more desirable, but cost of media/players will figure in the equation too. Look at the price of dual layer blanks, still overly high even this late in the market!
