Information-storage device including an oxygen absorbing device

摘要

An information-storage device comprises an information-storage medium, a transducer operable to write and to read information on the information-storage medium, and a sealed enclosure enclosing the same in an interior space containing an atmosphere comprising a gas mixture including a substantially inert gas and oxygen gas having a molar concentration between about 0% and about 10%. The sealed enclosure includes a base, a cover, and a seal that joins cover to base. The information-storage device may include at least one oxygen permeable component integrated with the sealed enclosure. The information-storage device further comprises an oxygen absorbing device operable to remove a substantial portion of oxygen gas from the atmosphere within. The oxygen absorbing device includes an oxygen absorbent material comprising oxygen-deficient cerium oxide, CeO2-x, where 0
