Glossary 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. 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. single-ended SCSI Signals are asserted on the bus by using a 5-volt signal referenced to ground. This method makes the bus somewhat susceptible to noise and loss of signal quality over distance. storage slot An area of the autochanger that holds cartridges when the cartridges are not in a drive or not being ejected through the mailslot. 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. 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 3
