Abstract: A cartridge for cleaning recording heads in a tape deck uses rotating brushes with a sweeping motion perpendicular to the direction in which tape travels over the recording heads. The brushes are connected through a gear train to the tape deck driving hub. The brushes and other elements are conductive, grounding static electricity generated by the cleaning operation.

Abstract: A data storage library is provided which comprises a housing with an access door provided therein. A plurality of cartridge storage arrays are mounted within the housing, wherein the front of each array is positioned to face an internal space of the housing, preferably occupied by a robotic arm. In this configuration, cartridges contained within the arrays are generally unable to be accessed by an operator. Of the plurality of cartridge storage arrays, at least one array is movable. A rotating mechanism is coupled to the movable array, and the rotating mechanism is operable to turn the movable array from a first position inside the housing and facing the internal space, to a second position inside the housing and facing at least partially away from the internal space, allowing cartridges contained within the plurality of cartridge storage arrays to be accessed by an operator through the access door.
