A Macintouch.com reader and MacBidouille notes that Apple has adopted a 
Sony drive for their Superdrive on the new iMac.  From Macintouch:

I just purchased a new 1.0 GHz iMac from an Apple store yesterday.  To  
my surprise the Apple System Profiler reported that the DVD drive was  
not a Pioneer drive, but instead is a Sony DVD RW DW-U10A.  Apparently  
this is a DVD-R, DVD-RW, DVD+R, and DVD+RW drive.  I had not been aware 
  that Apple changed DVD drive hardware venders.
   Apple has previously used a Pioneer drive in the past (for their 
"Superdrive"), which was limited to DVD-R and DVD-RW formats.

This MacRumors.com thread discusses the switch and confirms that the 
new iMacs use a Sony drive.

   Addendum: Some users report that their new iMacs still use the 
Pioneer drives, so it does not appear to be implemented across the 
line.
