An accommodating structure of data storage unit includes a carrier case formed by integrated injection molding. The carrier case is a plastic piece comprising a housing, a pair of elastic arms connected with the housing and a push block connected with the elastic arms. The housing has a receiving space, and the push block has a tab at a side away from the receiving space. Moreover, the present invention further provides an accommodating assembly of data storage unit. The components of the accommodating assembly are less and the structures are simple to enhance the convenience of assembly.

Provided herein is an apparatus including a disk drive base, wherein the disk drive base includes a first metal composition with a first CTE (coefficient of thermal expansion). A disk drive cover is attached to the disk drive base, wherein the disk drive cover includes a second metal composition with a second CTE that are different from the first metal composition and the first CTE. An arm is connected to a reader and a writer, wherein the arm is coupled to the disk drive base, the reader and the writer are separated by a distance, and the distance affects an MR (magnetoresistive) offset. In response to temperature changes between 0 C. and 60 C., the first material and the second material expand and contract comparably and proportionally. In further response to the temperature changes between 0 C. and 60 C., a change in the MR offset is less than 10% or a preferably defined range of a track pitch on a recording medium attached to the disk drive base.

An electronic device includes a sensing unit, a first control unit, and a second control unit. The sensing unit detects a parameter of the electronic device when the electronic device is tilted and sends a detection signal if the detected parameter exceeds the critical parameter. The first control unit and the second control unit receive the detection signal from the sensing unit. If the first control unit receives the detection signal before the second control unit, the first control unit controls the mechanical hard disk to power off and controls a magnetic head on the mechanical hard disk to reset from a working position to an original position. If the second control unit receives the detection signal before the first control unit, the second control unit controls the magnetic head on the mechanical hard disk to reset from the working position to the original position.

A rack enclosure system includes a receiving frame and a carrier. The carrier is configured to capture a storage device and to be slidably received by the receiving frame in a mounting direction. The carrier includes a first rail and a second rail each extending between a front end and a back end. The carrier also includes a cap member. The cap member may be rotatably or non-rotatably connected to the first rail at the front end. The cap is releasably connected to the second rail adjacent to the front end. The carrier further includes a handle with a cam portion and a latch portion. The cam portion is rotatably connected to the cap member and optionally the first rail. The latch portion is releasably connected to the cap member or the second rail.

Approaches to patching a leaky hermetically-sealed device include the use of a laminate rework patch that includes an adhesive tape layer, an aluminum sheet layer, and an outer cover layer, and whereby a viscous adhesive is injected or otherwise applied between the patch and the device leak location, over a layer of primer material, to fill the leak and stop the leakage of gas from inside the device. The thickness of the viscous adhesive, and thus the curing time and temperature of the viscous adhesive, can be managed by way of the thickness of the adhesive tape layer.

A fixing structure includes one holding member to be fixed to an electronic device. A hard disk is fixed to the holding member with a first vibration isolation member interposed therebetween, and a connection conversion board is fixed to the holding member with a second vibration isolation member interposed therebetween.

According to one embodiment, a disk device includes a disk-shaped recording medium, a head which processes data on the recording medium, and a housing accommodating the recording medium and the head. The housing includes a base with a side wall, and a cover having a welded portion welded to the side wall by laser welding. The welded portion includes a first welded portion welded to a first region of the side wall and having weld beads with a first shape, and a second welded portion welded to a second region of the side wall and having welded beads with a second shape different from the first shape.

The disclosure provides a hard disk drive chassis including a main body, fasteners and an engagement component. The main body is configured to be installed on a tray. The main body has two support surfaces and fixing structures. The two support surfaces face a same direction and are configured to support a hard disk drive, and the fixing structures are respectively disposed on the two support surfaces. The fasteners are respectively configured to be disposed through the fixing structures so as to be fixed to the hard disk drive. The engagement component is pivotably disposed on the main body and pivotable between an engaged position and a released position. When the engagement component is in the engaged position, the engagement component is configured to be engaged with the tray. When the engagement component is in the released position, the engagement component is configured to be disengaged from the tray.

A hard disc drive includes a base deck, a cover welded to the base deck, and a voice coil motor. The voice coil motor includes a first voice coil motor assembly and a second voice coil motor assembly. Either one or both of the first and second voice coil motor assemblies can be welded to the base deck.
