It doesn't really say anything about 'decompressed some of the files for faster loading after a HDD install' either so I would make neither of those assumptions.

Please don't say HDDVD is making a comeback again!!!

Is this just a minor tweak to the way the OS checks the disc or changes to the disc itself?

I think you meant to paste this link instead :s

http://en.wikipedia.org/wiki/Constant_angular_velocity

Later generation CD's DVD's and BD's use CAV for reading in data because a constant disc speed is required* for random access. Original 1x CD's used CLV for playing back music I believe? Can't find concrete source =(

*because waiting for a disc to speed up or slow down every time a read operation was requested would increase random access times from milliseconds (CAV) to seconds (CLV)!


TLDR: It's up to the drive itself whether it wants to use CLV or CAV to read in data, and one drive can support both modes. CAV is needed and preferred for data transfers because it's much friendlier to random access. CLV would be fine for stream playback (audio, video, data imaging).

I believe you have it backwards. The outside of the disc is moving at a faster speed than the inside.

EDIT: Looks like two others already posted this.

sounds like microsoft is trying to prevent pirating on their games which I don't blame them, they probably lost millions of dollars due to pirating.

There was me thinking this was the reason that disk drives can spin at different speeds, faster for when it is reading the one part of the disk, slower for when it is reading the other part of the disk, so that data is always read at about the same speed?

Interesting. Sounds interesting, although I doubt an extra gig will really affect the quality or length of very many games.

People can talk about how they are keeping a crappy platform going, but at this point it has to be making MS a ton of money. As long as the sales numbers on the hardware stay where it is at right now they will keep making them. Heck at this point in 2011 the 360 has actually sold more than in the last three years.
