T
tape cartridge A container holding magnetic tape that can be processed without separating the
tape from the container.
The library uses data, diagnostic, and cleaning cartridges. These cartridges are
not interchangeable.
tape drive An electromechanical device that moves magnetic tape and includes
mechanisms for writing and reading data to and from the tape.
tape drive tray assembly The mechanical structure that houses a tape drive, fan assembly, power and
logic cards, cables, and connectors for data and logic cables. Synonymous with
tape drive tray assembly.
tape transport interface
(TTI) An interface to control/monitor tape drive operation.
TTI
See tape transport interface.
V
vacancy plate A plate that covers an unused bay, such as a tape drive bay or power supply
bay.
W
wrist A component of the hand assembly that rotates the hand horizontally.
World Wide Name
(WWN) A 64-bit integer that identifies a Fibre Channel port. See also dynamic World
Wide Name (dWWN).
WWN See World Wide Name.
X
X carriage assembly A component of the robotics unit that moves the robotic hand assembly to and
from storage cells and tape drives.
X flex cable A signal cable that extends and retracts as the hand assembly moves forward
and backward on the X table.
X table assembly A component of the robotics unit that carries the hand assembly vertically
among the library modules.
Z
Z drive assembly A component of the robotics unit that moves the X table assembly vertically
among the library modules.
Z drive pulley A component of the Z drive assembly used to move the X table assembly
vertically along the Z pole to storage cells and tape drives.
Z flex cable The cable that carries control and power signals to the X table assembly. This
cable automatically adjusts to the position of the X table assembly in library.
Z pole The device that guides the vertical movement of the X table assembly.
Z reduction gear The component of the Z drive assembly that controls the Z drive pulley.
