Or BR disc made out of paper, which isn't going to shatter.
DiGuru said:BR on the other hand, allows you to make the disk from something like a very strong aluminium alloy, thereby making much higer and more stable rotation speeds possible.
In that sense, the HDDVD is already as fast as it will get.
PC-Engine said:BTW did you just grab that from a message board and pasted it here? It doesn't sound too professional of a post
Ty said:Err, don't take this the wrong way but why couldn't HD-DVD discs be made of different materials?
DiGuru said:Ty said:Err, don't take this the wrong way but why couldn't HD-DVD discs be made of different materials?
Theoretically, yes. But as the laser passes through the material, it would have to have the exact same optical specs. And that would be pretty hard to do, I think.
Ty said:But why can BR handle this and HD-DVD can't?
The 11% comment was made based on the initial price of production (11% of the price they currently are paying to make a single disc). The 10% number is what they think the discs will end up costing in a year or two (once disc mastering facilities are up and running and have been pumping out discs for a while).
We don't really know how much they cost right now to make, but it's easily possible that both numbers are correct (maybe 11% of current costs ends up being ~10% over dvd costs and they are hitting target sooner than expected? or maybe it still has some way to go). We don't have all the information, either way.

Anyway, BluRay is definitely going to be the format of choice because spies can encode data onto rice paper and if needs be, eat the evidence.

Sure if the glue is up to snuff...
TOKYO (AP) -- Japanese consumer electronics maker Sanyo Electric Co. has joined a group of companies led by Sony Corp. to develop recordable high-definition DVD disks, but will also remain allied with a rival group, a report said Tuesday.

Sanyo's decision to help both the Sony-led group and its competitor adds uncertainty to the race to develop a global standard for next-generation optical disks, which are expected to offer sharper images than current DVDs.
Sony leads a group promoting the Blu-ray Disc format, while Japan's Toshiba Corp. leads a rival group that backs the HD-DVD format.
Sanyo quietly joined the Blu-ray Disc side in April, while retaining its ties to the HD-DVD group, the Kyodo news agency quoted the company's officials as saying Tuesday. It plans to have a DVD player compatible with the HD-DVD format on store shelves later this year.
The news follows Toshiba's announcement last week that it is preparing to mass produce recordable high-definition DVDs with a 15-gigabyte storage capacity. Hitachi Maxell Ltd. and Mitsubishi Kagaku plan to market the new discs next spring, when Toshiba is scheduled to launch the new DVD recorders.
Sanyo plans to make a key part of the machines that reads the discs for both formats -- apparently hedging its bet, as the two groups pour resources into a technology that is expected to revolutionize Hollywood movies and consumer electronics.
A Sanyo spokesman couldn't be reached after the company's headquarters in the western city of Osaka closed for the day. At the Tokyo Stock Exchange, Sanyo shares fell 1 yen to 272 yen ($2.50).
Blu-ray has more capacity, with 50 gigabytes, compared to 30 gigabytes for HD-DVD read-only disks, but proponents of HD-DVD say their format is cheaper to make because the production method is similar to current DVDs.

Its starting to happen. I bet more companies will follow.
