Glossary
This glossary defines terms used in this guide or related to this product and is not
a comprehensive glossary of computer terms.
cartridge
A plastic enclosure that contains an optical disk. The cartridge is labeled “A” or “B” to denote
separate sides of the optical disk. The optical disk is never removed from the cartridge.
driver
A program that allows the operating system to communicate with a peripheral device.
element
A SCSI term for any one of the autochanger components — drive, mailslot, storage slots, or
picker.
jukebox
A term synonymous with optical disk library or autochanger. This type of optical storage device
is often referred to as a “jukebox” because when a file is requested, the disk containing the file
is found, inserted into the drive, and the requested information is sent to the host computer
system, similar to the way a musical jukebox finds a record and moves it to the turntable when a
song is requested.
jukebox controller
The part of the jukebox that controls the sending and receiving of SCSI commands, and controls
the disk transport mechanism.
LAN
Local area network. A group of computers and peripherals physically connected so users can
share hardware and software resources.
mailslot
The area where disks are inserted and removed from the jukebox.
multifunction drive
An optical disk drive that supports both rewritable and WORM optical disks. The drive detects
the disk type by reading a factory-stamped code on the disk, and automatically determines
whether to operate in rewritable or WORM mode.
