Microsoft may be beta-testing Xbox 360 DVDs that yield back about 15 percent storage space .According to DF’s source, Microsoft’s been using a 1GB DVD-Video partition on 7.95GB dual-layer Xbox 360 discs for “anti-piracy security sectors.” The new format in beta either minimizes or scraps that partition entirely, freeing those precious sectors up for developer use.
Final Fantasy XIII on two discs instead of three? Three discs with less crappy video compression? Extra songs in Dance Central 2 by Lady Gaga and Nelly Furtado?
The extra storage space probably wouldn’t be used for high-speed transfers,It is referring to a principle of optical media known as “constant angular velocity,” whereby data in the outer portions generally transfers faster than data stored near the center.
Microsoft’s labs almost certainly retains duplicates of any Xbox 360 DVD drives yet employed in production units, and would have the ability to perform far more reliable, deterministic tests on site. Xbox 360 games are routinely broken down and uploaded to torrent sites, sometimes days or even weeks in advance of retail launch. It stands to reason Microsoft’s giving up on the old scheme and dropping in something better.
In fact hackers are already rubbing their palms together. One named “Commodore4eva” wrote on IRC that the new anti-piracy scheme is called “xgd3,” and goads Microsoft to “bring it on.”
