low-voltage differential
SCSI A differential SCSI that
uses lower voltage swings and
is less susceptible to noise than
previous differential SCSI
signalling. LVD enables faster
data burst rates and longer
cable lengths. This form of
differential uses 3.3V signal
levels.

M-O
magneto-optical A type of
optical technology which uses a
laser to read from and write to
a magnetic layer on an optical
disk. To write, a spot on the
magnetic layer is heated by a
laser to a point where it can be
magnetically altered by the
write magnetic head. To read, a
light from the laser is reflected
from the spot. The magnetic
alteration causes the reflected
light to be polarized in one
direction (interpreted as a "1")
or the opposite direction
(interpreted as a "0").

mailslot The area where disks
are inserted and removed from
the jukebox.
multifunction drive An
optical disk drive that supports
both rewritable and write-once
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 write-once
mode.
optical disk A term
synonymous with the 5.25-inch
magneto-optical disk. There are
two types of optical disks used
in jukeboxes: rewritable and
write-once.

R-T
rear panel The rear panel of
the jukebox provides two SCSI
bus connectors that can be used
for either single-ended or
low-voltage differential bus
connections. The rear panel
also has the power connection
and switch.
