Detail of the perforation-to-disc binding system

Disc-binding is a variation of notebook binding that allow pages to be added, removed, and replaced easily; additionally pages can be transferred between disc-bound notebooks of different functions and sizes.

A page perforated for a disc-binding system contains a row of T-shaped cut-outs along the side edge of the page that grip onto the outside raised perimeter of individual discs. Pages can be added or removed at any time by peeling the perforations away from each disc.

As a result of the open nature of the binding mechanism, a number of resources for do-it-yourself planning and productivity management have adopted the system.

Currently there are several manufacturers of disc-binding systems: Levenger (under the brand name Circa), Rollabind, Myndology (Atoma), Staples (Arc), and Flic.

Origins and Patents[edit]

The disc-binding system was invented by Andre Tomas and Andre Martin (from whom the name of Atoma was derived). In 1948, they sold their patent to Georges Mottart, who founded Papeteries G. Mottart n.v., exclusive producer of disc-binding systems for Europe until the mid-nineties, when the patent expired. Currently, Atoma sells between 1 and 1.5 million Atoma notebooks.[1]

In 2007, the courts in Florida found that the extant disc-binding patents, obtained by Jacob Feldman in 1998, were invalid due to 'prior art' (amongst other issues) in that the patent was a modification of the disc-binding system Feldman was already importing to the US from Israel. On this basis, Levenger no longer owed royalties to Feldman, who now traded as Rollabind, and the system itself was open.[2]
