A modular data storage tape library includes a modular frame having a form factor similar to other types of computing racks. The modular data storage tape library includes a hermetically sealed enclosure within the modular frame and a cooling portion within the modular frame. Data storage tapes, data storage drives and robotics for moving the data storage tapes are included within the hermetically sealed enclosure. A heat exchanger transfers heat from the hermetically sealed enclosure to the cooling portion outside of the sealed enclosure through a boundary of the hermetically sealed enclosure without introducing air from the data center into the hermetically sealed enclosure. Because air is neither introduced nor removed from the hermetically sealed enclosure, humidity fluctuations are minimal, if existent, and contaminants are prevented from entering the hermetically sealed enclosure, thus increasing the life spans of the data storage tapes included in the hermetically sealed enclosure.

According to one embodiment, a magnetic recording/reproducing apparatus includes irreversible adsorbing materials in a sealed housing for the magnetic recording/reproducing apparatus.

A hard disk drive includes a base deck and a cover. The cover is coupled to the base deck to create an enclosure. The hard disk drive also includes tape that covers at least a portion of the cover and the base deck. The tape includes an adhesive layer, which includes an adhesive material and a moisture-absorbent material.

The present disclosure relates to disk separator plates that include a coating to increase the water contact angle of the exterior surface of the disk separator plate so as to decrease its wettability. The present disclosure also involves hard disk drives that include such a disk separator plate and related methods of forming such a coating.

The magnetic tape cartridge includes a magnetic tape that is accommodated in the magnetic tape cartridge while being wound around a reel hub. A water absorption amount of the magnetic tape measured after the magnetic tape cartridge is stored in a storage environment of a temperature of 32° C. and a relative humidity of 80% for 10 days is more than 0.30 g as a value in terms of a length of the magnetic tape of 1000 m, and the water absorption amount is a value measured in a measurement environment with a temperature of 21° C. and a relative humidity of 50% within 1 hour after the storage.

The present disclosure includes embodiments of an electronic device having a housing that defines an interior gas space, and desiccant disposed therein. The desiccant includes one or more zeolite compositions to manage the relative humidity of the interior gas space.

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.

The present disclosure relates to disk separator plates that include a coating to increase the water contact angle of the exterior surface of the disk separator plate so as to decrease its wettability. The present disclosure also involves hard disk drives that include such a disk separator plate and related methods of forming such a coating.

An electronic module ejecting mechanism includes a frame, a door pivoted to the frame, a rod, a sliding sheet slidably disposed on the door, a swing sheet, and a button connected to the sliding sheet. An electronic module is inserted into an opening of the frame. The rod is slidably disposed in the frame and has groove and bending ends. The swing sheet is pivoted to the sliding sheet and has a latch end for inserting into the groove end when the sliding sheet slides to a lock position. When the latch end is inserted into the groove end and the swing sheet swings to an expanding position with opening of the door, the latch end pulls the groove end to make the bending end push the electronic module to partially protrude from the opening. When the door continues opening outwardly, the latch end is separate from the groove end.

Provided is a magnetic recording and reproducing device including, in a sealed space in the magnetic recording and reproducing device: a magnetic tape; and a magnetic head are provided, in which a relative humidity difference (RH.sub.C-RH.sub.B) between a relative humidity RH.sub.B in the sealed space measured in an environment of a temperature of 21° C. and a relative humidity of 50% and a relative humidity RH.sub.C in the sealed space measured in an environment of a temperature of 60° C. and a relative humidity of 5% is within ±10%.
