Take-up Reel
The reel inside every DLTtape drive onto which DLTtape media
is wound. The in-the-drive take-up reel enables DLTtape systems
to operate using a single-reel cartridge and thereby pack more
tape and data into every cartridge.
TapeAlert
A firmware feature that monitors and returns the results of the
tape drive’s on-going self-diagnosis activity.
Tape Path
The path through which tape moves from the cartridge, past the
read/write head, and onto the take-up reel. The patented DLTtape
drive head guide assembly provides a gentle and solid path that
ensures tracking accuracy and long tape life.
TB
Terabyte. A unit of measure equal to 1000 Gigabytes (GB).
TCM
Tape Control Module. The SDLT TCM consists of a variety of
components; the most significant of these include the base plate,
the cartridge receiver, the tape supply motor assembly, the floor
plate assembly, and the buckling mechanism.
Termination
A physical requirement of the SCSI bus. A device that attaches to
both ends of an electrical bus and prevents reflection or echoes of
signals that reach the end of the bus.
Track
A linear or angled pattern of data written on a tape surface. DLT
and SDLT drives write information on multiple tracks
simultaneously.
Transfer Rate
The speed at which the data is transferred between a host (i.e.,
drive) and a recorded device. Usually expressed as bytes/sec or
bytes/minute.
TUR
Tape Unit Ready.
TUV
Technischer Uberwachungs Verein (German Safety Agency).
