Abstract
A data-storage cartridge comprises an outer shell having an inner surface. The data-storage cartridge also comprises a data-storage medium having an outer peripheral edge and a centrally-disposed hub. The data-storage medium is rotatably disposed within the outer shell so that the data-storage medium faces the inner surface of the outer shell. A recess is formed in the inner surface. The recess preferably extends from a first position proximate the outer peripheral edge of the data-storage medium to a second position proximate the hub. A liner is attached to the inner surface of the outer shell so that the liner covers a portion of the recess between the first and the second ends of the recess. The liner and the recess thereby form a passage for circulating air between the outer peripheral edge and the hub of the data-storage medium. This circulation minimizes the pressure differential across the data-storage medium, and thereby minimizes the vertical displacement of the data-storage medium caused by the pressure differential. The noted circulation also increases the airflow over the upper surface of the data-storage medium, and thereby reduces oscillations in the data-storage medium.
