Abstract:
A data-storage cartridge, comprising:an outer shell comprising (i) an upper half having an inner surface, the inner surface having a recess formed therein, the recess extending between a first position proximate an outer periphery of the inner surface and a second position proximate a center of the inner surface, and (ii) a lower half having a hub access opening formed therein, the hub access opening being substantially aligned with the center of the inner surface; a data-storage medium having a centrally-disposed hub and an outer edge, the data-storage medium being rotatably disposed within the outer shell so that at least a portion of the hub is positioned within the hub access opening and at least a portion of the outer edge is positioned proximate the outer periphery of the outer shell inner surface; and a liner positioned along the outer shell inner surface so that the liner covers a portion of the recess between the first and the second positions and the liner is substantially flat, the liner and the recess thereby forming a substantially unobstructed and enclosed passage having a first opening proximate the first position and a second opening proximate the second position for directing air toward the hub of the data-storage medium in response to rotation of the data-storage medium, whereby a difference in aerodynamic pressure across the data-storage medium is minimized.
