A little while ago, I looked at the Verbatim 52X retail CD-R spindles at Circuit City, and found out that all 6 I looked at were CMC spindles. You can get both MCC or CMC discs in these spindles, depending on the spindle--the MCC discs are much better in quality. By checking the outer hub serial number, one can determine the manufacturer of the discs in the store. The serial number on the CMC discs begin with CD-R 80 and end with a four digit number. The serial number on the MCC discs end with the string "AZO." I found that most (about 5-6 or so) of the spindles I saw at Best Buy tonight were the MCC spindles (serial number ending in AZO), while only 2 were the CMC spindles. I thought drpino would find this to be interesting. Like I've said in the past, if you buy the retail version of this media at Best Buy or Circuit City, you must be sure to get an MCC spindle. Otherwise, just buy the Verbatim DataLifePlus Super AZO labeled media online which is always MCC.
