A data storage disk cartridge library system includes a rack having an array of bays, at least some housing disk media cartridges and/or media drives, and a pair of horizontal and vertical guide rails bordering each bay. A media transport robot includes fixed-position drive wheels at each corner for driving the robot along the guide rails, and pivoting guide wheels corresponding to each drive wheel for guiding the drive wheel horizontally along a horizontal guide rail and vertically along a vertical guide rail. With each guide wheel coupled with a horizontal guide rail the robot can travel horizontally on the rack, and with each guide wheel coupled with a vertical guide rail the robot can travel vertically on the rack. Electrical power can be supplied to the robot via the guide rails, and gear portions of the wheels mechanically interface with a mechanical portion of the guide rails.

A case is provided. The case includes a housing, a cover and a restriction unit. The cover pivots on the housing, wherein the cover is adapted to be rotated relative to the housing. The restriction unit is connected to the cover and moveably connected to the housing, wherein the restriction unit is adapted to restrict the orientation of the cover. The user can thus easily maintain the electronic elements inside the case.

A storage drive assembly is provided. The storage drive assembly includes a storage drive sized and shaped for insertion into a slot within a chassis, a latching mechanism coupled to a first end of the storage drive, the latching mechanism including an actuation component actuable to transition the latching mechanism from a locked state in which the latching mechanism restricts displacement of the storage drive relative to the chassis to an unlocked state in which the latching mechanism enables displacement of the storage drive assembly relative to the chassis, and a drive secure cover plate adapted to removably mate with the latching mechanism in the locked state, the mated drive secure cover plate preventing physical access to the actuation component.

The apparatus includes a drive base, a drive cover overlying the drive base, wherein the drive cover comprises an opening therein, and wherein the drive cover is coupled to the drive base to enclose a media within an interior of the apparatus. A snubber is overmolded onto the drive cover. The media contacts the snubber during shock events.

A disk device includes a top cover and a disk medium with a recording surface. The top cover includes a center horizontal portion having a surface which extends from a center point of the disk medium along the recording surface to an outer peripheral portion, a curved portion having a surface which extends from the outer peripheral portion of the center horizontal portion in a direction away from the recording surface, and an outer horizontal portion having a surface which extends from the curved portion in a direction away from the center point and along the recording surface. The recording surface includes a first zone in which data is set to be written, and a second zone in which data is set not to be written, the second zone being disposed adjacent to the first zone on an outer edge side of the disk medium from the first zone.

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.

A shock absorbing screw includes a locking member, a friction member sleeved on the locking member, and a connecting frame sleeved on the friction member. The shock absorbing screw is connected to a hard disk by a connecting portion of the shock absorbing screw. An abutting portion of the shock absorbing screw is connected to the friction member. The connecting portion is passed through a second through hole defined in the friction member. A first end of the connecting frame includes a first clamping portion, a second end of the connecting frame includes a second clamping portion, and a second groove is defined between the first clamping portion and the second clamping portion. The shock absorbing screw is connected to a hard disk frame in the second groove. The friction member is connected to the connecting frame through a first through hole defined in the connecting frame.

A base member includes a recessed portion extending in radial directions and recessed upward from a lower surface of the base member, and a hole extending through the recessed portion in the vertical direction. The recessed portion includes a recessed portion loop-shaped surface defining a loop-shaped surface in the radial direction. A connector is located on a lower side of the recessed portion to cover the hole portion. An adhesive is located between the connector and the recessed portion. A minimum value of a gap distance in the radial direction between an outer end of the connector and an inner end of the recessed portion in which the outer end of the connector and the inner end of the recessed portion are opposed to each other with the adhesive therebetween is greater than a minimum value of a gap in the vertical direction distance between an upper surface of the connector and the recessed portion loop-shaped surface, in which the upper surface of the connector and the recessed portion loop-shaped surface are opposed to each other with the adhesive therebetween. The adhesive includes a filler.

A base unit includes a support to support a motor, a bottom plate, and a wall. The bottom plate extends radially outward from the support. The wall extends upward from an outer periphery of the bottom plate, and includes a rectangular opening in planar view. Surfaces of the bottom plate and the wall include a cover surface covered with an electrodeposition coating film and an exposed surface in which a material of the base unit is exposed from the electrodeposition coating film. At least an upper end surface of the wall and a partial region of an inside wall surface of the wall continuous with the upper end surface are each the exposed surface.

A cover plate for locking a chassis includes a first cover section provided on top of the chassis, a second cover section provided on top of the chassis and having a positioning pin, and a resilient lock defining a through hole corresponding to the positioning pin. When the resilient lock is in a first position, the positioning pin is latched in the through hole, one end of the first cover section abuts against one end of the second cover section, and the cover plate is locked. When the resilient lock is in a second position, the positioning pin is removed from the through hole, the first cover section is slid toward the second cover section, and the cover plate is unlocked.
