Provided are devices, and methods for use with devices, that generate oxygen from residual humidity within a sealed enclosure that is filled primarily with an inert gas. A PEM electrolyzer that is configured to generate oxygen from residual humidity is situated within the sealed enclosure. The PEM electrolyzer includes a PE membrane disposed between an anode and a cathode, and further includes a hydrogen getter. The hydrogen getter helps the PEM electrolyzer to be a net producer of oxygen. Exemplary sealed enclosure devices include hard disk drives such as HAMR hard drives filled primarily with helium.

Devices and methods for generating oxygen from residual humidity within sealed enclosures

Electronic devices that include a composition that can generate a gaseous oxidizing agent component; and a generating device configured to actively cause the composition to generate the gaseous oxidizing agent component. The generating device includes at least one metal-air battery that is in electrical communication with a power source that is configured to apply power to the metal-air battery according to a predetermined time interval to recharge the metal-air battery to generate the gaseous oxidizing agent component.

Electronic device that includes a composition that can actively generate and release a gaseous oxidizing agent component into an interior space of the electronic device, and related subassemblies and methods

An electronic device including a housing having an interior gas space, at least one electronic component positioned within the housing, an environmental control module positioned within the housing, wherein the environmental control module contains a sorbent, and a relative humidity sensor in communication with the interior gas space, wherein the interior gas space is maintainable at a relative humidity of 0% as measured by the relative humidity sensor. The interior gas space may include between about 97% and about 99.9% helium expressed as a molar fraction and at least a portion of the remainder as molecular oxygen. The sorbent can include at least one of a type A zeolite, a type X zeolite, or a type Y zeolite.

Zones of a magnetic recording medium are allocated as a respective plurality of distributed media caches arranged in a predetermined order. For each of a plurality of caching events, cache data is written to one or more of the distributed media caches. A next of the media caches in the predetermined order is selected for the next caching event.

Distributed media cache

Zones of a magnetic recording medium are allocated as a respective plurality of distributed media caches arranged in in a predetermined order. For each of a plurality of caching events, cache data is written to one or more of the distributed media caches. A next of the media caches in the predetermined order is selected for the next caching event if the selected caches are not a last in the predetermined order. Otherwise a first media cache is selected in the predetermined order.
