Cliff is right is saying it is a disc drag. I would call it a "Gear Drag" or a "Gear Disc Drag". It is confusing to call it a disc drag as that indicates it has a much better drag than it has. It in fact uses a small disc for the breaking but it also uses gearing. A lot of manufactures have called these disc drags so people think they are getting a super drag. The true large diameter disc drag and a caliper drag is much superior to the drag in this reel. The picture shows a true disc drag in an Abel reel.
