All 3495 ATLDS models can have an optional high-capacity input and output facility (Figure 1, item 1 ) that reserves a section of the cartridge storage area to be used for input and output of large numbers of cartridges. This optional facility requires that the tape library be placed in paused mode (indicating that the cartridge accessor is not active) while the areas are being loaded and unloaded. The software term for the process of ejecting cartridges into the high-capacity output station is known as bulk eject, and the software term for the process of entering cartridges into an automated tape library dataserver using the high-capacity input station is known as bulk entry.
