lift drive assembly A component of the robot that moves the table assembly vertically among the

library modules.

lift drive pulley

A component of the lift drive assembly used to move the table assembly vertically

along the lift pole to slots and tape drives.

lift-flex cable

The cable that carries control and power signals to the table assembly. This

cable automatically adjusts to the position of the table assembly in the library.

lift pole

The device that guides the vertical movement of the table assembly.

lift reduction gear

The component of the lift drive assembly that controls the lift drive pulley.

lift suspension

cables

Four cables used to lift and lower the table assembly among the library modules.

load port

A device in the library that allows an operator to insert or remove tape

cartridges during library operations.

logical library

A virtual representation of a physical library. Also called virtual library partition.

LTO

Linear Tape-Open. A technology that creates tape drives and tape cartridges

based on common specification, licensing, and compliance standards and

allows tape device users to use tape products and tape cartridges from various

sources. Ultrium 460 tape drives (LTO-2) are HP’s second generation of LTO tape

drives and the Ultrium 960 tape drives (LTO-3) are third generation tape drives.

magazine

A removable array that holds tape cartridges and is placed into the load port.

PCI

Peripheral component interconnect. The PCI bus typically runs at speeds of 33

MHz or 66 MHz and is usually 32 bits wide. This means that it passes 32 bits

of data simultaneously as if down 32 separate wires. Some of the most recent

computers include wider 64-bit PCI buses, and already certain very high-end

video capture cards offer improved performance if connected to a 64-bit PCI

bus.

picker

The portion of the picker assembly that grasps and holds a tape cartridge.

picker assembly

A part of the library robot whose function is to grasp tape cartridges and move

them between slots and tape drives. A bar code scanner on the hand assembly

reads tape cartridge volume labels.

put

An activity in which a robot places a tape cartridge into a slot or tape drive.

PWA

Printed wiring assembly.

reach mechanism

A component of the robot that moves the gripper to get or put a tape cartridge

at a designated location.

robot

An electro-mechanical device that transports tape cartridges to and from

locations in the library.

robotics unit

The unit that includes the robotics components and that controls the movement

of the robot between slots, tape drives, and load ports.

RS-232C

Short for Recommended Standard-232C, a standard interface approved

by the Electronic Industries Association (EIA) for connecting serial devices.

This standard is for asynchronous transfer between computer equipment and

accessories. Data is transmitted bit by bit in a serial fashion. The RS-232

standard defines the function and use of all 25 pins of a DB-25 type connector.

slot

The location in the library in which a tape cartridge is stored.

slot database

The tape cartridge and slot records collected by the library inventory.

suspension cable

One of four cables used to raise and lower the table.
