  • Publication number: 20100085660
    Abstract: A tape library apparatus includes a transporting rail extending in parallel with a vertical reference plane. A cell is configured to receive a tape cartridge in an upright attitude along an inclined reference plane. The inclined reference plane intersects with the vertical reference plane at an acute angle for establishment of a vertical intersection line within the vertical reference plane. A transporting unit is configured to change its attitude between a parallel attitude and an inclined attitude. The transporting unit in the parallel attitude allows insertion and withdrawal of the tape cartridge in the upright attitude along the vertical reference plane. The transporting unit in the inclined attitude allows insertion and withdrawal of the tape cartridge in the upright attitude along the inclined reference plane.

  • Patent number: 6540167
    Abstract: A control mechanism for loading/unloading data storage tape is provided. The control mechanism is part of a tape drive that receives a removable tape cartridge. The tape cartridge stores the data storage tape that is movable using the control mechanism. The control mechanism includes a plurality of gears, together with a cam. A leader assembly is operably connected to the control mechanism. At least portions of the leader assembly are movable in connection with loading or unloading the data storage tape relative to the leader assembly. A leader pin is joined to an end of the data storage tape. When the loading operation is performed, portions of the leader assembly are moved generally linearly into the tape cartridge and then the control mechanism causes such portions to pivot in order to engage the leader pin and remove it from its seat. When the unloading operation is performed, the portions of the leader assembly are moved in substantially opposite directions from the loading operation.

  • Patent number: 6144520
    Abstract: A storage apparatus including a drive unit for performing access of data on a cartridge recording medium; at least one cell for storing the cartridge recording medium, the at least one cell being inclined downward toward an interior portion of the storage apparatus. The storage apparatus has a housing having an opening for allowing direct insertion of the cartridge recording medium from outside of the storage apparatus into the at least one cell, and allowing for direct ejection of the cartridge recording medium from the at least one cell to the outside of the storage apparatus. An accessor is provided for transferring the cartridge recording medium between the at least one cell and the drive unit. A string screw is threadedly engaged with the accessor, and is rotationally driven by a motor.

  • Patent number: 6023391
    Abstract: A storage apparatus including a drive unit for performing access of data on a selected one of a plurality of cartridge recording media; a cartridge storing member for storing the plurality of cartridge recording media; and an accessor for taking the selected cartridge recording medium out of the cartridge storing member, and feeding the selected cartridge recording medium to the drive unit. The cartridge storing member has a plurality of cells through which the cartridge recording media are allowed to be respectively inserted and passed toward the drive unit. Each of the cells includes a latch for positioning the cartridge recording media into a transfer position wherein the cartridge recording media is transferred to the accessor; improper insertion preventing means for preventing full insertion of the cartridge recording media into cells in an improper orientation; and a shutter mechanism including a door which is allowed to be opened only when a given cartridge recording media is inserted and ejected.

  • Patent number: 5581522
    Abstract: A library apparatus having an accessor equipped with a bar code reader. The library apparatus includes a recording medium drive unit for writing and reading data to and from a recording medium cartridge; a cartridge entry unit for entering recording medium cartridges into the apparatus; and an automatic cartridge exit unit for automatically ejecting recording medium cartridges from inside the apparatus. The accessor transports cartridges through the cell unit, the recording medium drive unit, the cartridge entry unit and the automatic cartridge exit unit. The library apparatus also includes a door for allowing a large number of recording medium cartridges to enter all at once into the cells of a given cell column of the cell unit. Because the accessor is equipped with the bar code reader, the bar code of each cartridge is read thereby every time a cartridge is taken out of its cell by the accessor.
