The tape cartridge autoloader library system comprises at least one read/write tape drive, a tape cartridge picker, a single tape cartridge interface, and at least one pair of tape cartridge transport magazines within a compact form factor that fits into a standard library rack mount of cabinet. The autoloader/library system is a complete tape cartridge library that stores, manages, and automatically exchanges a plurality of tape cartridges between the tape drive unit, the single cartridge interface, and the tape cartridge transport magazines. The tape cartridge transport magazines are each configured to receive and store a plurality of individual tape cartridges in a horizontal relationship. The tape cartridge transport magazines also transport the individual tape cartridges within the tape cartridge transport magazine so that a specific one of the tape cartridges is in position for selection by the cartridge picker. The cartridge picker is configured to rotate to position the cartridge picker to exchange the individual tape cartridges with one of the tape drive, the tape cartridge transport magazines, and/or the single tape cartridge interface. The single cartridge interface is configured to receive individual tape cartridges for either storage in one of the tape cartridge transport magazines or read/write operations in the tape drive.

An EMI shielded enclosure has a plurality of electrically conductive walls. The conductive walls are electrically connected so electromagnetic radiation from within the enclosure cannot radiate through the walls. An EMI shield plate, that makes up at least one wall of the enclosure, is an electrically non-conductive, plastic wall with tunnel holes through the wall. The holes provide for air flow into and out of the enclosure. A conductive coating on the non conductive wall and the holes converts the non-conductive plastic wall into a conductive wall with waveguide attenuating. The waveguide attenuating holes, when so coated with the conductive layer, attenuate electromagnetic radiation passing from inside the enclosure through said holes to outside the enclosure. The waveguide attenuating holes effectively attenuate electromagnetic radiation at frequencies up to 5 gigahertz.

A connection structure between a disk drive housing and a rack to eliminate a source of vibration, and hence improve the performance of the disk drive. An interference-fit tab and slot vibration reduction structure is described, where the tab is formed on the housing and the slot is formed on the shelf. The tab and slot vibration reduction structure includes a disk drive having an outer housing, the housing having a bottom surface. A tab extends from the bottom of the housing. A shelf is provided on the rack system for receiving one or a plurality of disk drive housings, and one slot is formed in a front edge of the shelf for each drive housing. When the disk drive housing is positioned on the shelf with the tab positioned in the slot to create an interference fit, the housing is rigidly attached to the shelf.

An anti-slamming latch is described for removably installing a module housing into a bay in a frame having a predetermined width. The module housing has a guide pin on a front portion thereof projecting from said housing. The latch apparatus comprises a latch body supported from the frame allowing straightforward removal and insertion of a rear portion of the module housing into said bay. The latch body has a first channel therein adapted to receive and engage the guide pin when the body is in a first position. This channel has a closed end engaging the pin to prevent insertion of said module housing past a predetermined intermediate position in the bay. The latch body has a second channel intersecting the first channel forming a rounded protuberance therebetween. The module may not be further inserted by pushing on the module. It may only be fully inserted in the bay by moving the latch body from the first position to dislodge the pin from the closed end of the first channel, move the pin over the rounded protuberance, and into the second channel in the body. Movement of the latch body levers the pin along the second channel, and thus the module into full insertion, to a second closed position wherein the pin is fully within in the second channel in the latch body.
