Universities in Germany put 500GB in one DVD, claim 1TB is possible
The University of Berlin, partnered with the Budapest University of Technology and Economics, as well as Universita Politecnica delle Marche in Italy, have found a way to squish 500GB of data into one HD DVD.
Under normal methods of storage, a Blu-Ray disk holds 25GB of data. An HD-DVD holds 15GB, and a dual layer HD-DVD holds 30GB. However, the universities have managed to modify where the recording laser puts the data. By "using nanostructures inside the disk rather than on the surface as in conventional optical storage systems", the Microholas project has found a way to put 500GB onto one HD DVD. The universities look forward to pushing this project to it's full potential, which could mean a Terabyte of data on a single HD-DVD disk.

you spin me right round right round like a record baby right round

no more of having to go to meatspin to get my fill!
Imagine if the receptionist lost 500gb of company data on the way to work!!!!! that is a lot of info for someone to get their hands on.....
It would suck waiting 4 hours for the thing to burn too...... HAahaaa
Aerial density means that the drive can spin SLOWER to achieve the same performance. Anyone heard of perpendicular recording drives? Same RPM but much faster reads and writes. Same reason when the craptors came out a set of them in RAID was then and still is slower at sequential reads and writes than two higher capacity drives.
RPM is only good for access time, IE a few MS of seek time, aerial density is good for more data transfer per second. Yes data transfer does go up with speed, but not as much as it does for higher density drives.
Go look at our HD tach benchmark thread.
Or compare.
Writing speeds for DVD were 1x, that is 1350 KB/sec
Note that for CD drives, 1x means 150 KB/sec, 9 times slower.
Blu-Gay . . . what was that?? 8-Track?? (sorry I had to, its Sony ;)
