Double Density Discs, up to standards?

[130T|_|L15/\/\]

I am quite curious on the double density CD-R discs which hold 1.3 gigs. Sounds like a double sided 650mb disc. Anyone ever use these? More importantly are these 1.2 mm thick?? They seem interesting, I wouldn't mind having to flip over the disc if it were like that. Even nicer if it is in CD-RW. Oh I saw these on the Sony website. The double density seems to be similar to the 9.4 gig DVD-R, which is double sided. Any ideas on if it is widely supported? Comments welcome!

-TIA

they only work in the drive they were burned in....and probably won't be supported by anyone else as there is really no point as DVD burners are getting so cheap these days....4.7GB beats 1.3 anyday 8)

I agree. There will be no point in getting that. and besides, I don't think they'll last long on the market compeeting with dvd capacity.

Get dvd burner instead.

BTW, the way they got 1.3 Gig on the disks was to wind the data track tighter in the disk.....you could think of it as a bigger version of the 90 and 99 minute CD-R's, rather than some sort of DVD technology.

They are not double-sided. They look for all the world like ordinary CDs.

However, they are not "CDs". They cannot be read by ordinary CD players and can only be written to by the Sony DD-CD drive.

As they use a different burning method, you cannot make audio CDs or VCDs on them. Only DATA discs.

Thanks for clearing that up. Sounded too good to be true.
