General Information

It's mostly found on games from central Europe and the late 90s.
Identification
Discs with this protection carry 2 or 3 very large (cm sized) physical rings totalling between 10k to 50k sectors. They also have associated dummy files called ".prt".
All discs seem to be from the same ifpi L171 plant. Note though that kdg/Koch discs don't always carry mastering SIDs.

Additional Information
An outlier also by KDG but with a very different ring configuration has been found to. How this fits into the rest is currently unknown.
