I have one Verbatim 16X 50 pack from Staples that has code MCC 03RG20, and one 100 pack from meritline MCC 03RG20. Everything from the packaging, to the disc label, to the meidia code, are identical. Both are from Taiwan.
The inside of the disk is silver on the 100 pack, and on the 50 pack the inside looks more like a Taiyo Yuden (a small clear ring).
Simply put: how could the same model have different disks under identical Verbatim labels?
