MSE
Multi-mode Single-Ended is a signaling alternative for multi-mode SCSI
devices that allows multi-mode SCSI devices to operate while SE SCSI devices are
present on the bus.
MTBF Mean Time Between Failures.
N
Native Capacity The capacity of a given media product in its basic recording
format (without the use of data compression).
Native Mode Refers to the uncompressed storage capacity of a media subsystem.
(See Native Capacity.)
P
Peripheral A device added to a system as a complement to the basic central
processing unit (CPU), such as a disk drive, tape drive, or printer.
POST Power-on Self-Test. When power is applied to the tape drive, it performs a
POST.
PRML Partial Response Maximum Likelihood is a method for converting the
weak analog signal from the head of a magnetic disk drive into a digital signal.
R
Restore To replace data on the hard drive with data obtained from another
media device.
RoHS Restrictions on Hazardous Substances is an EU directive that restricts, and
in some cases bans, the use of certain compounds in the manufacture of electronic
equipment. RoHS mandates that new electrical and electronic equipment put on
the market does not contain lead, mercury, cadmium, hexavalent chromium,
poly-brominated biphenyls (PBB), or poly-brominated diphenyl ethers (PBDE).
S
SATA Serial Advanced Technology Attachment. A Serial ATA International
Organization (SATA-IO) standard for the interface between a computer and
peripheral controllers.
SCSI Small Computer System Interface. An American National Standards
Institute (ANSI) standard for the interface between a computer and peripheral
controllers.
SE Single-ended SCSI Mode. A term referring to the electrical characteristics of
the signal used on the SCSI bus interface. For each signal that needs to be sent
across the bus, there exists a wire to carry it. SE SCSI uses one line for each signal,
with all lines using a common ground reference.
Server A powerful computer system with a large tape drive capacity that serves
the information access and communication needs of multiple users.
