im talking about those discs that were sent out that were the halo reach game, the ones that were supposed to hold more data? just wondering cause i dont remember hearing anything else about these new discs.
They've been in use for a while. I think Gears 3, Rage, Witcher 2, Skyrim, Batman Arkham City, Mass Effect 3 all use it.
You can spot these new discs because they still spin in the disc drive for a time even if you have installed the game in question. Also, they are about a 1 gig larger than the old format (7 gigs or so compared to the old ones that usually topped out at around
The new disc format has been in use with every title, since the last major dashboard update.
The DVDs don't actually hold any more data (as dual-layer Xbox360 DVDs hold a standard 7.95GB), but Microsoft trimmed back some DRM sectors and updated drive firmware to be able to access the extra GB that freed up. The discs aren't physically any different.
They're just accessed in a different way.
Well, the only way the discs could hold more data, is if the laser diode was blue, like the Xbox HD-DVD external player etc.. (the Blue laser Diodes, have to be more focused in HD-DVD Drives too..)

The video part of the disc, what you see when putting the disc in a regular DVD player, used to be around 1gb in size. Microsoft greatly reduced that and as such freed up most of that space to be used for game data.
Also they now press data closer to the edge of the disc, which allows even more space to be used.
This is why they had a beta for the new disc layout (they sent people copies of Halo Reach on the new format), the update for them flashed the dvd drives firmware, and pirates can not write the discs correctly as a home burner can not write as close to the
edge as the pressing allows.
