Take-up Reel
Super DLTtape media is wound. The in-the-tape drive take-up reel
enables DLTtape and Super DLTtape systems to operate using a single-
reel cartridge and thereby pack more media and data into every
cartridge.
A firmware feature that monitors and returns the results of
TapeAlert™
the tape drive's on-going self-diagnosis activity.
The path through which media moves from the cartridge, past
Tape Path
the read/write head, and onto the take-up reel.
The Tape Control Module implements the functions required to

buckle and unbuckle the media and control the media motion.
A physical requirement of the SCSI bus. A terminator is a
Termination
device that attaches to both ends of an electrical bus and prevents
reflection or echoes of signals that reach the end of the bus.
A linear or angled pattern of data written on a media surface.
Track
SDLT tape drives write information on multiple tracks simultaneously.
The speed at which the data moves between a host (that is,
Transfer Rate
tape drive) and a recorded device. Usually expressed as bytes/sec or
bits/sec.
Transistor-to-Transistor Logic is a class of digital circuits built from
TTL
bipolar junction transistors (BJT), diodes, and resistors. It is the base for
the semiconductor integrated circuit (IC) technology.
