DLT-S4 Product Manual 151

Shelf Life

The length of time that media can be stored without losing its

magnetic strength. For Super DLTtape II media, this period is 30 years or

more.

SI The International System of Units.

TB Terabyte. Equal to 1,000,000,000,000 (10

) bytes. This is the

International System of Units (SI) definition used by telecommunications

engineers and storage manufacturers.

Take-up Reel The 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.

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 media moves from the cartridge, past

the read/write head, and onto the take-up reel.

Termination 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.

Track A linear or angled pattern of data written on a media surface.

SDLT tape drives write information on multiple tracks simultaneously.

Transfer Rate 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.

UL Underwriters Laboratories is a testing laboratory, which develops

standards for consumer products, chiefly dealing with product safety.

Unformatted Capacity 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.)

Ultra320 An DLT-S4 tape drive SCSI interface that provides a low-

voltage differential (LVD) mode running up to 160 MB/sec.

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

to a computer.
