Glossary
barcode reader A component of the robot that is used for cartridge identification and position
calibration.
cartridge The plastic housing around a cartridge tape. A plastic leader block is attached
to the tape for automatic threading when loaded in transport. The spine of the
cartridge contains a label listing the volume identification number.
cell The slot in the magazine that is used to store a tape cartridge.
Class A digital
device Class A equipment is intended for commercial installation.
Class I laser
product Class 1 lasers are products where the power of the laser beam produced (the
accessible emission) is always below the Maximum Permissible Exposure value.
Therefore, for Class 1 lasers the output power is below the level at which it is
believed eye damage will occur. Exposure to the beam of a Class 1 laser will
not result in eye injury. Class 1 lasers may therefore be considered eye safe.
cleaning cartridge A tape cartridge that contains special material to clean the tape path in a
transport or drive. Ultrium cleaning cartridge labels have a CLN prefix.
CLI Command Line Interface
daisy chaining Parallel SCSI peripherals can be daisy chained together. Each device has a
second port used to connect the next device in line. The last device in the chain
must be terminated.
data cartridge A term used to distinguish a cartridge onto which a tape drive may write data
from a cartridge used for cleaning purposes.
drive The device that the device uses to record data onto tapes.
drive bay The space where the drive module resides.
drive cleaning A device feature that uses a cleaning cartridge to clean a tape drive.
drive module The entire assembly that houses the drive, including the metal housing and
connectors.
encryption The process of changing data into a form that cannot be read until it is
deciphered, protecting the data from unauthorized access and use.
ESD Electrostatic discharge. The release of static electricity from one conductor to
another.
Ethernet A local-area, packet-switched network technology. Originally designed for coaxial
cable, it now also runs over shielded, twisted-pair cable. Ethernet is a 10 or 100
Megabytes-per-second LAN.
