Abstract
A cartridge for a disk-shaped storage medium, wherein the cartridge has partition walls within the cartridge for separating the storage medium from other portions of the cartridge, thereby protecting the storage medium from damage due to debris particles. The partition walls are formed by ribs which protrude from the interior surfaces of each half of the cartridge. The ribs do not meet but rather define a small gap between them. The top of one rib has a V-shaped protrusion (taken perpendicular to the length of the rib) while the top of the other rib has a complementary V-shaped groove. Elongate debris particles are blocked from passage into the compartment containing the storage medium due to the tortuous path defined by the gap.
