Abstract: 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.

Abstract: 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.

Abstract: 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.
