A magazine management device stores a plurality of magazines in which a plurality of optical discs is housed. The magazine management device includes a case that supports the plurality of magazines, a plurality of partitions that divides the case so as to form a plurality of regions in which the magazines can be stored one by one, an antenna that transmits a radio wave for asking a radio identifier provided to the magazine for a response and receives a radio wave of the response transmitted from the radio identifier, and an arithmetic processor that receives information obtained from the radio wave of the response received by the antenna.

According to an embodiment, a cassette storage case includes a body defining an internal storage space for a cassette. The body includes a lower body part, and a shield body part extending upward from an upper surface outer region of the lower body part. The shield body part has an opening in an upper portion thereof. A load protruding portion extends outward from an outer bottom surface of the lower body part, and has a shape that corresponds to a shape of the opening.

There is provided a tape cartridge housing case, the case including (1) a case body having an upper wall portion that covers an upper face of a tape cartridge, a lower wall portion that covers a lower face of the tape cartridge, and an opening that the tape cartridge is inserted and removed through, (2) a first protrusion that is formed at an inner face of the lower wall portion, and that anchors an anchored portion, (3) a recess that is formed at an outer face of the lower wall portion at a position so as to be on the opposite side to the first protrusion in a front face-back face relationship, and (4) a second protrusion that is formed at an outer face of the upper wall portion at the same position as the recess in plan view.

A data storage library system includes at least one data storage library comprising at least one library frame and at least one environmental conditioning unit, the at least one environmental conditioning unit configured to control one or more environmental conditions within the at least one library frame. The system further includes at least one access door for providing access to an interior portion of the data storage library, a library controller, and at least one warning indicator associated with the data storage library and in electronic communication with the library controller. The at least one warning indicator is configured to provide an indication to an operator when the conditions within the data storage library are such that the at least one access door may be opened and when the conditions within the data storage library are such that the access door should not be opened.
