Embodiments provide a terminal, and the terminal includes a body, a cover body covering the body, a circuit board mounted in the body, a central processing unit welded on the circuit board, a control part mounted on the cover body, and a protection switch welded on the circuit board. A hard disk slot for accommodating a hard disk is disposed in the body. The cover body is detachably mounted on the body, and is configured to seal the hard disk in the hard disk slot. The cover body is opened to drive the control part to open the protection switch. An electrical signal variation is generated due to opening of the protection switch. After detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk.

An example apparatus, such as a vibration testing tool, includes: a housing configured to fit into, and to connect to, a test slot configured to house a device for testing, with the test slot being part of a device test system; accelerometers connected to the housing and configured to output signals representing movement of the apparatus; and circuitry connected to the housing to generate data based on the signals, with the data being usable to determine multiple independent accelerations of the apparatus.

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.

Described herein is a system that includes a hard disk drive. The hard disk drive includes a base and a cover welded to the base by a weld bead. The base and the cover form a hermetically sealed housing. The system further includes a shield, coupled to an exterior of the hermetically sealed housing over the weld bead. The shield also is spaced-apart from the weld bead.

Disclosed is an electronic digital postcard device comprising, a body housing a display, the housing defining a dimension of the device, where the dimension is at least one dimension of a postcard, and a port configured to receive an electronic media presentation, the electronic digital postcard being configured to store and playback a received electronic media presentation. Further, a method of delivering a digital postcard is disclosed.

A magnetic tape cartridge includes a substantially rectangular box shaped case that houses, inside a housing area, a single reel wound with a magnetic tape and equipped with a reel plate that is attracted and held by magnetic force when loaded into a drive device, and a metal-containing block that is disposed inside the case and outside the housing area of the reel, and has a proportion of metal by mass to a total mass of metal provided inside the case including the reel equipped with the magnetic tape and the reel plate of 18% or greater.

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.

A cup portion of a base member includes a cylindrical portion and a bottom plate portion. The cylindrical portion is arranged to be coaxial or substantially coaxial with a central axis extending in a vertical direction. The bottom plate portion is defined integrally with the cylindrical portion, and is arranged to close a lower portion of the cylindrical portion. A bearing mechanism is arranged inside of the cup portion. An outer circumferential surface of the bearing mechanism and an inner circumferential surface of the cylindrical portion have an adhesive layer arranged therebetween. In one preferred embodiment of the present invention, a communicating hole passing through the cylindrical portion in a direction that crosses an axial direction is defined in the vicinity of a junction of the cylindrical portion and the bottom plate portion. In another preferred embodiment of the present invention, the base member includes a communicating hole passing through the bottom plate portion in the axial direction.

Provided is a video recorder including a case body comprising a space for housing a plurality of electronic parts, the plurality of electronic parts including: an optical disk drive (ODD) holder attached to an ODD; and a hard disk drive (HDD) holder attached to an HDD; a front panel on which a front printed circuit board (PCB) is mounted and which covers a front side of the case body; and a rear panel on which a rear PCB is mounted and which covers a rear side of the case body.
