Abstract: A thin base member for use in a disk drive apparatus in which a bearing mechanism and an actuator are arranged includes a plurality of lower recess portions, a C-shaped smooth surface, and a fan-shaped recess portion. The C-shaped smooth surface is arranged in a region of an upper surface of the base member to at least partially encircle the region where the bearing mechanism is arranged and the C-shaped smooth surface has a height constant or substantially constant in a circumferential direction. At least a portion of each of the lower recess portions is provided below the C-shaped smooth surface, in which the C-shaped smooth surface has a cross section positioned at the lower recess portions to protrude in a direction toward which the upper surface of the base member faces or in a direction toward which the lower surface of the base member faces.

Abstract: The present invention relates to a HDD base comprising: at least two anchor formations for anchoring at least two parts of a HDD; and a rigid member configured to retain anchor formations in a fixed position relative to each other.

Abstract: A hard disk drive mounting frame for supporting hard disk drive includes a bottom plate and two side plates extending upwardly from the bottom plate. The side plates and the bottom plate corporately define a receiving space to receive the hard disk drive. Each of the side plates defines a plurality of hard disk drive supporting holes. Hard disk drive securing screws pass through the hard disk drive supporting holes to engage with the hard disk drive. The bottom plate defines a plurality of frame supporting holes, the frame supporting holes is located directly under the hard disk drive and covered by the hard disk drive, frame securing screws pass through the frame supporting holes to secure the hard disk drive mounting frame to outer environment. An electronic using the hard disk drive mounting frame is also provided.

Abstract: Improved hard disk drives of the invention comprise a composite housing, wherein the composite housing comprises a base and a cover, wherein at least a portion of the composite housing comprises a laminate of at least one rigid plastic layer and at least one metal coating. Methods for forming the same are also disclosed.

Abstract: There is provided a base for a motor, the base including: a base body formed of a steel plate through a pressing process; and an outer wall part defining an exterior of the base body, in which the outer wall part has a thickness smaller than a thickness of the steel plate in order to increase a contact area with a sealing part.

Abstract: Systems and methods for providing adsorptive surface coatings on internal components of a storage drive to adsorb contaminants are provided. One such system relates to a storage device including a magnetic media configured to store information, a head configured to read information from the media and to write information to the media, and at least one internal component selected from the group consisting of an internal surface of a housing of the storage device, a recirculation filter, an anti-disk, an actuator arm for moving the head, and a voice coil motor, where a contaminant adsorptive coating is disposed on a portion of the at least one internal component, where the contaminant adsorptive coating is configured to bond with preselected contaminants.

Abstract: A disk drive device is provided with a base, a hub on which a recording disk is to be mounted, a bearing unit arranged on the base and configured to rotatably support the hub, and a spindle drive unit configured to rotatably drive the hub. A circumferential ring wall portion is arranged on the outer circumference of the base and formed of a plastic.

Abstract: A hard disk drive of the invention comprises: a housing comprising a base and a cover; an insert positioned on an interior surface of the base of the housing for stabilization of one or more components within the hard disk drive during operation of the hard disk drive, wherein the insert is relatively stiff as compared to stiffness of the base; and the at least one of the one or more components mounted on the insert. Methods for forming such hard disk drives and hard disk drive rack assemblies comprising the hard disk drives are also disclosed.
