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.

According to one embodiment, a disk device includes a housing including a base with a bottom wall, a drive motor including a pivot erected on the bottom wall and a hub rotatably supported around the pivot, ten or more magnetic disks attached to the hub and stacked on a flange of the hub, and spacer rings attached to the hub and each disposed between each respective adjacent pair of two magnetic disks. A number of the spacer rings is one less than the magnetic disks. At least one spacer ring has a thickness different from that of the other spacer rings, and a difference between a maximum thickness and a minimum thickness of the spacer rings is 0.01 mm or more and 0.09 mm or less.

An electronic device with a storage function is provided. The electronic device includes a main connection bolt and a housing. The housing includes a first housing member and a second housing member. The first housing member includes two hooks and a fastening portion. The second housing member includes two wedging portions and a fastening base. The hooks are wedged into the wedging portions to restrict the freedom of the first housing member to move relative to the second housing member in a first direction. The main connection bolt connects the fastening portion to the fastening base in a second direction to restrict the freedom of the first housing member to move relative to the second housing member in the first direction. The first direction is perpendicular to the second direction.

According to one embodiment, a disk device includes a disk-shaped recording medium, a base accommodating the recording medium, the base including a bottom wall, a sidewall on a peripheral portion of the bottom wall, and a rib on a part of an upper surface of the sidewall and extending along an entire circumference of the sidewall, a first cover on a part of the upper surface of the sidewall, and a second cover on a first surface of the rib and above the first cover. The rib includes a first region with a first width, a second region with a second width less than the first width, and the first surface with a fixed width around an entire circumference of the rib. The first region and the second region are located corresponding to a side portion of the recording medium.

Provided is a heat-dissipating, shock-absorbing structure which is applicable to an electronic module with a hard disk drive. The heat-dissipating, shock-absorbing structure includes a heat-dissipating frame, an elastomer, and a plurality of heat conduction layers. The heat-dissipating frame has a fixing segment and two extending segments. The extending segments connect with two ends of the fixing segment. The fixing segment connects with one side of the hard disk drive. The distance between the extending segments is greater than the thickness of the hard disk drive. At least a portion of the elastomer is disposed at the extending segments. The heat conduction layers cover the elastomer.

A retention assembly includes a first retention member with a first set of ribs and a second set of ribs. The first set of ribs are positioned to form slots, which are shaped to receive data storage devices. The first set of ribs are arranged to separate adjacent data storage devices and have a first length. The second set of ribs extend into respective slots to form air channels within the slots, and the second set of ribs have a second length that is shorter than the first length.

According to one embodiment, a disk device includes a housing including a base with a bottom wall, a drive motor including a pivot erected on the bottom wall and a hub rotatably supported around the pivot, ten or more magnetic disks attached to the hub and stacked on a flange of the hub, and spacer rings attached to the hub and each disposed between each respective adjacent pair of two magnetic disks. A number of the spacer rings is one less than the magnetic disks. At least one spacer ring has a thickness different from that of the other spacer rings, and a difference between a maximum thickness and a minimum thickness of the spacer rings is 0.01 mm or more and 0.09 mm or less.

According to one embodiment, a disk device includes a recording medium of a disk form, a magnetic head, a housing, and a first protective member made of a resin. The recording medium includes a recording layer. The magnetic head is configured to read/write information from/to the recording medium. The housing includes a base provided with an inner chamber in which the recording medium and the magnetic head are accommodated, a cover that covers the inner chamber, and a welded part at which the base and the cover are welded to each other. The first protective member is located outside the housing, to cover at least part of the welded part.

A hard disk drive enclosure base includes a non-uniform disk shroud surface extending from a top to a floor, the shroud surface including a first portion having a first radius and clearance along the circumference of the shroud surface and a second portion having a lesser second radius and clearance. The second portion of the shroud surface may be positioned at multiple locations where the drive form factor is especially constraining and in view of the need for a sufficient seal land surface for applying a gasket seal around the perimeter of the inner cavity of the base part. Widening the disk shroud clearance where possible can reduce the shear stress exerted at the disk edges thereby reducing the windage drag and associated disk spindle motor power consumption, especially in the context of helium-filled drives in which disk flutter is less of an issue.

A disk device includes a magnetic disk, a magnetic head configured to read information from and write information to the magnetic disk, a housing having a mounting space in which the magnetic disk and the magnetic head are mounted, a substrate, and a sensor. The housing includes a wall and a hole extending therethrough to the mounting space. The substrate is attached to an outer side of the wall and sealing the hole. The sensor is mounted on the substrate.
