A deep slot cell configured to house a plurality of tape cartridges. The deep slot cell includes a front side of the deep slot cell configured to allow insertion and removal of a locking tape cartridge of the plurality of tape cartridges by a robotic mechanism. The deep slot cell includes a depth side of the deep slot cell configured with an opening to engage a locking mechanism that prevents a biasing spring mechanism of the deep slot cell from advancing a rearmost tape cartridge of the plurality of tape cartridges forward toward the front side of the deep slot cell. The deep slot cell includes a front air gap at the front side of the deep slot cell that prevents the robotic mechanism from reaching a front-most tape cartridge of the plurality of tape cartridges after the robotic mechanism removes the locking tape cartridge from the deep slot cell.

In an approach for preventing damage to a tape library, a processor receives a first sensor reading, wherein the first sensor is located within a tape library. A processor receives a second sensor reading, wherein the second sensor is located external to the tape library. A processor determines that the second sensor reading is greater than or equal to the first sensor reading. A processor receives an indication that a door to the tape library is open. Responsive to receiving the indication that the door to the tape library is open, a processor disables a fan.

An enclosure configured to at least partially surround at least one access opening that permits access to an interior of a data storage library, wherein the enclosure includes at least one side surface configured to surround the at least one access opening to form a chamber and to permit access to the interior of the data storage library. The enclosure also includes at least one access opening in the at least one side surface to permit access to an interior of the chamber, wherein the enclosure is configured to selectively acclimate the chamber between environmental conditions exterior of the enclosure and environmental conditions of the interior of the data storage library.

Provided is a recording tape cartridge including: a case that is configured by causing a peripheral wall of an upper case and a peripheral wall of a lower case to abut against each other and accommodates a reel on which a recording tape is wound; a reference surface that is formed on the lower case and serves as a reference in an axial direction of the reel in a case where the case is loaded into a drive device; a noncontact communication medium on which individual information is recorded, the noncontact communication medium being accommodated in the lower case and having a plate shape; a supporting portion that is formed on the lower case and supports the noncontact communication medium such that the noncontact communication medium is disposed while being inclined with respect to the reference surface at an angle of approximately 45 degrees; a position restricting portion that is formed on the lower case and restricts a position of a lower end portion of the noncontact communication medium; and a retaining portion that is formed on the lower case and retains an upper end portion of the noncontact communication medium.

The magnetic recording medium includes a non-magnetic support, a magnetic layer including a ferromagnetic powder on one surface of the non-magnetic support, and a back coating layer including a non-magnetic powder on the other surface of the non-magnetic support, in which a difference (S.sub.after−S.sub.before) between a spacing S.sub.after measured by optical interferometry regarding a surface of the back coating layer after methyl ethyl ketone cleaning and a spacing S.sub.before measured by optical interferometry regarding the surface of the back coating layer before methyl ethyl ketone cleaning is greater than 0 nm and equal to or smaller than 30.0 nm, and the non-magnetic support is an aromatic polyamide support having a moisture absorption of 2.2% or less.

Disclosed are a data disaster recovery storage device and a carrier. The data disaster recovery storage device comprises: a housing; a fire-resistant shell; a liner; an internal data line; and a memory. The memory is connected to the internal data line, and is suspended inside the liner. The water absorption resin is filled at the outer side of the memory. According to the present invention, a plurality of thermal insulation and heat-dissipation means are used for ensuring the safety of the memory during vehicle burning. The memory is mounted in a suspended manner, and is not in direct contact with other structures, which can effectively avoid direct heat conduction, and effectively perform shock absorbing. The invention utilizes the property that water boils at a constant temperature under the standard atmospheric pressure, and uses a method for storing water in a liner shell to ensure that the memory is not damaged at a certain external high temperature within a certain period of time.

A recording medium cartridge according to an embodiment of the present technology includes: an information recording medium; a first cartridge memory; and a second cartridge memory. The first cartridge memory is capable of storing first information relating to the information recording medium, and includes a non-contact communication medium capable of reading/writing the first information via a first communication device disposed in a drive device. The second cartridge memory is capable of storing second information relating to the information recording medium, and is configured to be capable of reading the second information via a second communication device.
