laser will not result in eye injury. Class 1 lasers may therefore be

considered eye safe.

Class II laser product

Class 2 lasers are limited to a maximum

output power of 1 mW. A person receiving an eye exposure from a

Class 2 laser, either accidentally or as a result of someone else's

deliberate action (misuse) will be protected from injury by their

natural blink reflex. This is a natural involuntary response which

causes the individual to blink and avert their head thereby

terminating the eye exposure.

D DLT

Digital Linear Tape technology is owned, developed, and

manufactured by Quantum Corporation. DLT tape drives use half-

inch wide tape. DLT 8000 tape drives record on 208 tracks

(uncompressed).

E Elements

SCSI designation for any device or bin in the library

that can hold a cartridge. SCSI elements include storage bins, tape

drives, load port bins, and the gripper.

EMI

Electro-Magnetic Interference refers to unwanted electrical

noise present on a power line. This noise may "leak" from the

power lines and affect equipment that isn't even connected to the

power line. Such "leakage" is called a magnetic field. Magnetic

fields are formed when unwanted noise voltages give rise to noise

currents. Such noise signals may adversely affect electronic

equipment and cause intermittent data problems.

ESD

Electro-Static Discharge

G Gripper

A mechanical component of the extension axis assembly

(robotics) which grips and holds a tape cartridge in transit

GUI

An ATL touch screen Graphical User Interface is made up of

bit-mapped graphics displays resembling tabs and buttons,

designed to act as the library’s main console for receiving

information and inputting commands.

HHost

The device or devices to which the library is connected.
