How does one determine the manufacturer of the disc?
There 2 methods of determining the manufacturer of the disc. Method 1: Read the stamper number on the disc. Each company has a distinct stamper number that is unique for each company. The stamper number should be located near the protruding inner ring on the reading surface, as shown below. But this method is difficult to determine the manufacturer unless one is familiar with the companys coding scheme. Method 2: There are programs that can be used to read a code placed within the disc itself that distinguishes the manufacturer of the disc. One program is DVDInfo Pro. This programs can allow the end-user to read the MID (Manufacturer Identification). All discs are required to have a MID placed within the disc and this requirements is for both DVD+R/+RW formats and the DVD forum formats.
