QUANTUM DLTtape HANDBOOK
G.19
Thin Film.
A type of coating allowing very thin layers of magnetic
material used on tape drive read/write heads. Media with thin film
surfaces can store greater amounts of data.
Track.
A linear or angled pattern of data written on a tape surface.
DLTtape drives write information on multiple tracks simultaneously.
Track-To-Track Seek Time.
The time required for the read/write
heads to move to an adjacent track.
Transfer Rate.
The rate at which the drive sends and receives data
from the controller. Usually measured in megabytes per second.
A DLT 8000 drive, for instance, has a native transfer rate of
6MB/s.
U
Unformatted Capacity.
The total number of usable bytes on the
media, including the space that will be required later to record
location, boundary definitions, and timing information. See also
formatted capacity.
V
Volume.
The quantity of information written on a piece of media.
Typically measured in megabytes or gigabytes.
