The embodiments of the present disclosure relate to a solid state drive. According to embodiments of the present disclosure, the solid state drive may include a notch fastening part in which a notch connecting the solid state drive and a platform outside the solid state drive is fastened, a coupling part coupled to the socket of the platform, and a bottom plane that is a printed circuit board (PCB) plane that forms a cavity between the top plane of the platform when the coupling part is coupled to the socket of the platform.

A drive carrier for retaining a persistent storage drive in an enclosure. The drive carrier includes a mounting bracket, a handle coupled to the mounting bracket, and an electromagnetic interference (“EMI”) shielding apparatus disposed between mounting bracket and at least a portion of the handle. The mounting bracket is shaped to be coupled to the persistent storage drive. The EMI-shielding apparatus includes a plurality of EMI-shielding fingers. Each EMI-shielding finger includes a lower surface, an upper surface that is approximately parallel to the lower surface, and a contoured surface extending between the lower surface and the upper surface.

A carrier for a storage device is provided. The carrier includes an accommodation bracket, a panel and an electromagnetic shielding element. The accommodation bracket has an open space. The panel has a handle. The electromagnetic shielding element is disposed between the accommodation bracket and the panel. The electromagnetic shielding element is engaged with the accommodation bracket.

A tray device includes a tray body and a bracket mounted on the tray body. The tray body includes at least one connecting plate, a resilient sheet, and a handle assembly. The resilient sheet is coupled to the at least one connecting plate. The handle assembly includes a handle, a rotating shaft, and a snap hook. One end of the handle is hinge-mounted to the at least one connecting plate through the rotating shaft. The snap hook is located on the handle. The handle is fixed to the at least one connecting plate through the snap hook.

A ring-shaped glass spacer is configured to be arranged in contact with a magnetic disk in a hard disk drive apparatus. A surface resistivity of a surface of a glass material of the glass spacer at 22 (° C.) is lower than a surface resistivity of an inner portion of the glass material at 22 (° C.).

Disclosed herein are printed circuit boards (PCBs) with patterned ground structure filters and data storage devices comprising such PCBs. Each PCB comprises a resonator having an L-shape or a zig-zag shape in a plane of the printed circuit board and at least one signal trace. The resonator has a first dimension and a second dimension in the plane of the printed circuit board. A portion of the at least one signal trace is situated over the resonator and is separated by a distance from the resonator by a dielectric material. In some embodiments, at least part of the portion of the at least one signal trace extends in a same direction as the first dimension (in the case of an L-shaped resonator) or tracks the zig-zag shape of the resonator (in the case of a zig-zag-shaped resonator).

A disk drive includes a metal base that has a rectangular bottom wall and side walls formed on each side of the rectangular bottom wall, the side walls including a first side wall on a shorter side, a metal cover that is fixed to the metal base with a plurality of metal screws, including two screws disposed at opposite ends of the side wall, a gap being formed between an upper end of the first side wall and the metal cover, a magnetic disk disposed on the metal base, at a position offset from a center of the metal base in a longitudinal direction towards the first side wall, and a head. The first side wall and the metal cover are electrically connected at an intermediate position of the first side wall between said opposite ends of the first side wall.

The present disclosure generally relates to a shielded three-layer patterned ground structure in a PCB. The PCB may be disposed in a hard disk drive. To reduce costs, PCBs are being made with only four total layers separated by dielectric material. Conductive traces in PCBs can have the problem of common mode current flowing through the traces and thus increasing the magnitude of EMI noise. By providing a shielded three-layer patterned ground structure, not only is the cost reduced, but so is the common mode current and the magnitude of EMI noise, all without any negative impact to the differential signal.

An electromagnetic leakage prevention device includes a bottom surface, first side walls, second side walls, a first connecting portion, and a second connecting portion. The first side walls are coupled to a side of the bottom surface. The second side walls are coupled to a side of the bottom surface opposite the first side walls. The first connecting portion is coupled to ends of the first side walls away from the bottom surface. The second connecting portion is coupled to ends of the second side walls away from the bottom surface. A distance between the first side walls and the second side walls increases along a direction away from the bottom surface.
