The International System of Units.

S

tatic RAM. A memory chip that requires power to hold its content.

T

he reel inside every tape drive onto which DLTtape or 

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 the tape 

drive’s on-going self-diagnosis activity.

The path through which media moves from the cartridge, past 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 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. SDLT tape 

drives write information on multiple tracks simultaneously.

The speed at which the data moves between a host (that is, 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 bipolar 

junction transistors (BJT), diodes, and resistors. It is the base for the 

semiconductor integrated circuit (IC) technology. 

Test Unit Ready (see also 

).

Underwriters Laboratories is a testing laboratory, which develops standards 

for consumer products, chiefly dealing with product safety.

The total number of usable byes on the media, including 

the space that will be required later to record location, boundary definitions, and 

timing information. (See also Native Capacity.)

A tape drive SCSI interface that provides a low-voltage differential 

(LVD) mode running up to 160 MB/sec and a single-ended (SE) mode running up 

to 40 MB/sec. 

Universal Serial Bus is a serial bus standard for connecting devices to a 

computer.
