in jukeboxes: rewritable and write-once.
optical disk library See jukebox.
R-T
rewritable optical An optical disk
technology in which data can be
repeatedly written using magneto-
optical reading and writing technology.
SCSI An acronym for the Small
Computer Systems Interface. See
Appendix B for a more detailed
explanation of SCSI and SCSI buses.
storage slot An are of the autochanger
that holds cartridges when the cartridges
are not in a drive or not being ejected
through the mailslot.
terminator A resistor array device used
for electrically terminating a SCSI bus.
A SCSI bus must be terminated at its
two physical ends. A peripheral device
uses a terminator only if it is at the end
of the bus.
W
write-once An additional operating
mode available with multifunction
drives. When a write-once disk is
inserted, the drive will write data, but
will not write over data that has been
previously written. This feature is
useful for applications that need
permanent data security and audit trails.
write protect A feature that prevents
data from being written to a disk. A
write protect tab is located on both sides
of the optical disk cartridge to enable
write-protection on one or both surfaces
of the disk.
