As far back as
this report from SPOnG in January 2006, issues with Xbox 360s scratching game discs have dogged the console. Microsoft even started a replacement service, charging $20 to replace scratched first-party games.
Now, the
Seattle Post Intelligencer reports Hiroo Umeno, a Microsoft program manager, stating in a declaration relating to a class action suit that information regarding drives scratching discs "information that we as a team, optical disc drive team, knew about. When we first discovered the problem in September or October (2005), when we got a first report of disc movement, we knew this is what's causing the problem."
This is the line that has been picked up on around the Internet. However, Umeno also states (in the
declaration that you can download in PDF form here.) "[G]yroscopic precession force is what causes the disc to unchuck, which is what we’ve . . . known. In order for the force to act on the disc, the assembly, the console and the disc drive, which is inside the console, has to move relative to the rotation of the disc".
So, you've got to move the console while the disc is in the drive and moving? Microsoft's
most recent statement on the matter is, "Xbox 360 is designed so that it will not damage a game disc as long as the console is not moved while the disc is spinning.
"Too much movement of any game console, not just Xbox 360, can cause scratches on a disc. That's why we put a warning on the face of the disc tray, which the user has to physically remove before the initial use of the system. We also have warnings posted online and in hard copy instruction manuals."
Apparently this has resulted in 55,000 complaints and/or returns, to which Microsoft responds, "While we have had some users contact us with concerns about scratched discs, it is less than one-half of 1% of the total Xbox 360 user base".
The case continues...
