This type of protection is not disk based, but something that came with a game that you had to make up items on the wheel and enter data into the game for it to start.
So you could usually copy the disk easily, but need this device to play.
The most famous example is the code wheel from the Secret of Monkey Island.
Some others include
Bard’s Tale III
Monkey Island 2
Out of this World
Pool of Radiance
Secret of Monkey Island
