Strange, I've been having the same problem on all the CDs I've gotten
from Apple since last May or so.  While all the older CDs seem to read
fine, the _develop_, 7.0, and Developer series have had a hard time
being read.

However, this can be fixed by cleaning the lens on your CD-ROM drive!!
I've been opening the drive and reaching in with a Q-tip (not for the
faint hearted), but I think a standard CD lens cleaning disk would also
do the job.  After cleaning the lens, these disks read fine (for a few
weeks, anyway).  If you still have your fan connected, you'll probably
need to do this every week or two.  Without the fan, it still sometimes
needs to be done.

I don't understand why just these recent disks are so sensitive.  I
suppose it's something in the manufacturing process.
