A device to detect hot-plugging and hot-unplugging of hard disk and the hard disk type includes a connector and a control circuit. When hot-plugged, the hard disk is coupled to the connector, the control circuit comprises delay circuit and latch circuit. The delay circuit delays a falling edge of the third signal and outputs a delay signal, the latch circuit processes the first and second signals and outputs a logical result as a latch signal. The control circuit determines the connected or disconnected status and type of the hard disk according to the respective levels of the first and second signals, the delay signal, and the latch signal. The delay signal and the latch signal work to correct error of the control circuit in determining connectivity and non-connectivity during a session due to asynchronous changes in signal levels of the first and second signals.

An archival data storage system library includes magnetic-recording disk media, a storage enclosure in which the media are housed, data storage devices (DSDs) configured to write to and read from the media, an automated disk handling mechanism configured to transfer at least some of the media between the storage enclosure and the DSD, and a hermetic enclosure containing the foregoing components. The storage system may further include a gas circulation system for filtering contaminants from the hermetic enclosure. Such a storage system may be implemented as a rack-mountable unit, or as an entire cleanroom facility, as well as in intermediate form factors between those. In the context of a cleanroom storage system, the system may further include an automated disk handling shuttle to receive the media from the disk handling mechanism and an automated disk loading mechanism for accessing the media from the shuttle for installing into the DSD.

A hard disk fixing device according to an embodiment of the present disclosure includes a hard disk box, a baffle and a snap. A first end of the baffle is rotatably installed on a first side edge of the hard disk box, a first end of the snap is rotatably installed on a second side edge of the hard disk box, and a second end of the snap is engaged with a second end of the baffle. As such, the hard disk box, the snap and the baffle form an accommodating cavity to limit a hard disk, and the accommodating cavity can accommodate the hard disk.

A hard disk holder includes an integrated sheet metal framework. The integrated sheet metal framework is a main body structure of the hard disk holder, and a head and a tail of the integrated sheet metal framework are clamped to form a closed framework. The integrated sheet metal framework specifically includes a first side plate, a head end plate, a second side plate, and a tail end plate that are formed by sheet metal and are disposed in sequence. An inner side of the first side plate and an inner side of the second side plate each have a limiting bulge, and the hard disk body has limiting holes. The limiting bulges adapt to the limiting holes. When the hard disk body is mounted to the hard disk holder, the limiting bulges extend into the limiting holes to form a limiting structure.

A device carrier for an information handling system includes a latch, an interface, lights located on a front of the latch, and first and second light pipes. The latch holds the device carrier within the information handling system. The first light pipes are located within the latch, and provide light to the lights located on the front of the latch. The second light pipes are located within the interface and the latch, and provide the light to the first light pipes. The location of the second light pipes enables the same brightness of the light provided to the lights when a long device is inserted within the device carrier as compared to when a short device is inserted within the device carrier.

A first terminal provided on a tail pad portion includes a base portion, a bent portion and an overlapping portion. The base portion includes a first surface fixed to a base insulating layer and a second surface on an opposite side to the first sur face. The bent portion is reversed in a thickness direction of the base portion from an end of the base portion towards the second surface. The overlapping portion extends from the bent portion in a direction along the second surface. An ansotropic conductive film (ACE) is disposed between the overlapping portion and the second terminal. The overlapping portion and the second terminal are connected to each other via the ACE.

A drive carrier for a device of an information handling system includes first and second portions. The first and second portions are placed in physical communication with the device. The first portion includes first and second side rails to secure the device within the drive carrier. The first and second side rails slide within a first slot of a bay of the information handling system. The second portion is located on top of the first portion and floats away from and toward the first portion when the drive carrier is inserted with the bay of the information handling system. An amount of float for the second portion is based on a bay pitch of the bay.
