A data storage system may include multiple data storage devices, such as hard disk drives, a cooling fan, and a sound balancer structure between the fan and the drives. The sound balancer is intentionally positioned where it substantially balances, about the center of rotation of and along at least one axis of a fan-facing storage device, the sound pressure from the fan that impinges upon the fan-facing face of the storage device. This redistribution of the sound pressure suppresses sound pressure-induced torque upon and therefore rotational vibration of the storage device, which in turn enhances the track following capability of the storage device.

The present invention relates to a combined record player, wherein analog audio players are positioned on a top portion or a side portion of a cabinet, a digital audio player is positioned on a front portion of the cabinet, a first PCB is positioned on a front portion or a bottom portion of the cabinet, a second PCB is positioned on a rear portion of the cabinet, and an analog audio output interface is positioned on a rear surface of the cabinet; the first PCB contains an analog-to-digital signal converter, the second PCB contains a digital-to-analog signal converter, the analog audio players are electrically connected to the analog-to-digital signal converter, the digital audio player is electrically connected to the digital-to-analog signal converter, the analog-to-digital signal converter is electrically connected to the digital-to-analog signal converter, and the digital-to-analog signal converter is electrically connected to the analog audio output interface. The invention can integrate the analog audio players and the digital audio player within a cabinet where electrical wires between components in the cabinet do not interfere with each other and keep neat, and both the first PCB and the second PCB have a larger heat dissipation space.

Embodiments of the present disclosure provide a method for managing a storage device and a storage device, the storage device including a chassis and a hard disk assembly. The method comprises: receiving a signal indicating a position of the hard disk assembly relative to the chassis, the hard disk assembly being slidably coupled to the chassis, and the signal being generated by an electromechanical element disposed on the hard disk assembly; and controlling a rotating speed of a fan based at least in part on the signal, the fan being disposed in the chassis and configured to blow wind to the hard disk assembly.

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.

An example system may comprise a network-attached storage device including a base station having a hardware interface including a drive port and a connectivity port; a modular storage drive attachable to and detachable from the drive port; and a modular wireless adapter attachable to and detachable from the connectivity port. The portable storage device is formable by detaching the modular storage drive and the modular wireless adapter from the hardware interface of the network-attached storage device, and coupling the modular storage drive and the modular wireless adapter to one another via a portable hardware interface. Further, a rechargeable modular power unit is removable from the base station and attachable to and detachable from a power port of the network-attached storage device.

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.

An adaptable chassis having an upper box chassis structure including a power supply. The upper box structure includes side walls to receive at least one component sled and registration features. A lower box structure includes side walls to receive at least one component sled. The lower box structure includes a registration feature to engage the registration feature of the first chassis structure. The lower box structure includes a power connector to obtain power from the power supply. The lower box structure may be replaced with large capacity structures when additional component sleds need to be added since the power supply resides in the upper box structure.

A data storage system includes multiple hermetically-sealed enclosures containing a lighter-than air gas, multiple data storage devices housed in each enclosure and containing the lighter-than-air gas, a tray pneumatic control system each corresponding to and pneumatically coupled to a corresponding hermetically-sealed enclosure, and a rack pneumatic control system pneumatically coupled to each tray pneumatic control system. The tray pneumatic control system may include a tray valve operable in a first way to provide a vacuum in a space between first and second sealing members of the enclosure, and operable in a second way to provide the lighter-than-air gas to the enclosure. The rack pneumatic control system may include a vacuum source operable to provide a vacuum to each tray valve and a lighter-than-air gas source operable to provide the lighter-than-air gas to each tray valve.

A storage apparatus includes one or more chassis including a first housing for a chassis fan and a second housing for a plurality of storage devices. A plurality of modules have at least either one storage device or a storage device fan. Module connectors supporting each of the modules are provided so that the modules can be freely attachable/detachable. A fan air intake port that guides air outside the chassis to the chassis fan is formed in the first housing; and a fan air exhaust port that exhausts air in the chassis to outside of the chassis is formed in the second housing; wherein some module of the plurality of modules is configured of a storage device module in which the one storage device is modulized; and another module which is configured of a module which is at least either a fan-equipped storage device module or a fan module.

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.
