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

The present disclosure relates to electronic devices that include a composition that actively generates a gaseous oxidizing agent component within the interior gas space of the electronic device. The present disclosure also involves related methods.

Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck, a plurality of storage mediums, and a plurality of disc separator plates. Each disc separator plate includes one or more mounting pad surfaces, at least one of the surfaces having a protrusion. The disc separator plates are coupled to one another and the base deck via the mounting pads, with the disc separator plates in a stacked arrangement. The protrusion or protrusions facilitate alignment of the plurality of disc separator plates in the stacked arrangement, and mitigate contact between the storage mediums and the disc separator plates.

A media separator plate is provided having a plate main body and a shroud. The plate main body has a continuous, non-interrupted inner circumference and a continuous, non-interrupted outer circumference. The plate main body extends from the inner circumference to the outer circumference and includes a top surface and a bottom surface. The shroud is integrally formed with at least a portion of the outer circumference of the plate main body. The shroud is configured to at least partially surround the plate main body. The shroud extends above the top surface of the plate main body, below the bottom surface of the plate main body and outwardly from the outer circumference of the plate main body.

An apparatus which provides improved positional control for an access element moveable adjacent a rotatable surface, such as a data transducing head adjacent a data recording disc in a data storage device. The apparatus comprises a fluidic stripper with one or more cantilevered arms which project proximate a corresponding array of one or more rotatable surfaces. Each arm comprises an edge surface which extends proximate to and in facing relationship with a movement path of an access element across the associated rotatable surface to impede fluidic currents established by rotation of the rotatable surface. Each arm further supports a ramp structure which receivingly supports the access element at a position away from the rotatable surface and proximate the innermost diameter during a deactivated mode when the rotatable surface is stationary.

Fluidic stripper assembly with load/unload ramp

An apparatus which provides improved fluidic control includes a circumferentially extending windage plate adapted for placement adjacent a rotatable disc surface. The plate operates to direct fluidic currents established by rotation of the surface. One or more snubber members are supported by the plate to prevent localized contact between the plate and the surface as a result of deflection induced by application of a mechanical shock. Preferably, an access element is moveable along a movement path adjacent the rotatable surface. An air dam comprising a localized increased thickness portion of the plate at a leading or trailing edge of the plate preferably further directs the fluidic flow, and the snubber member-further prevents contact between the air dam and the rotatable surface. The rotatable surface preferably comprises a data recording surface and the access element preferably comprises a data transducing head.

A limit stop filter support apparatus for use in controlling fluidic currents and limiting movement of an actuator within a housing, such as in a data storage device. First and second filter retention members extend from a filter support base to confine opposing ends of a filter used to filter fluidic currents within the housing, and a cantilevered limit stop extends from the base to contactingly limit movement of an actuator moveable within the housing. The limit stop preferably comprises a spring member supporting a latch member, the latch member selectively confining the actuator in a parked position. The first and second retention members each preferably include a shroud surface adjacent an outer peripheral edge of a rotatable storage medium to direct the fluidic currents established by rotation of the medium.

Limit stop filter support apparatus

A plenum assembly for use in a data storage device to direct and filter recirculating currents established by high speed rotation of a recording disc. The plenum assembly includes a top plate and a partitioning wall which projects from the top plate to form opposing, longitudinally extending first and second chambers. A first portion of the recirculating currents is directed along the first chamber and a separate, second portion of the recirculating currents is directed along the second chamber. A recirculation filter transversely extends across the first and second chambers and intersects the partitioning wall so that the respective first and second portions of the recirculating currents concurrently pass through adjacent sides of the recirculation filter before exiting the plenum assembly and merging into a combined set of recirculating currents.

A base support member for a disc drive is provided. The base support member includes a disc support cavity configured to house and support a spinning disc, and a component support cavity configured to house and support a set of electrical and mechanical disc drive components. The base support member also includes at least one surface that defines an airflow channel that is generally disposed within the component support cavity of the base support member. The airflow channel has an inlet opening positioned in a first location proximate the disc support cavity and an outlet opening positioned in a second location proximate the disc support cavity. The airflow channel is configured to receive a flow of air from the spinning disc at the inlet opening and to discharge the flow of air at the outlet opening.

A stationary disc separator plate for use in a disc drive to suppress turbulence near a disc drive read/write head used to read data from and write data to a rotatable disc. The stationary plate is supported adjacent the disc and has substantially circular inner and outer circumferences. A leading edge and a trailing edge of the plate define an open portion to accommodate radial movement of the head adjacent the disc. A trailing edge air dam disposed at the trailing edge of the plate diverts a substantial portion of an airflow generated by rotation of the disc away from the open portion to reduce an airflow velocity at the head. In disc drives having multiple discs, a plate is preferably disposed between each pair of adjacent discs. Air vents preferably extend through the thickness of the plate to reduce aerodynamic drag and hence power consumption by the drive.
