Ways of Selecting Density
Using CompacTape III the density defaults to 10.0 GB native. The only selection is for
this cartridge is 2.6, 6.0 10.0 compression off or 20.0 GB compression on.
Using the CompacTape III the user can select density by using any of the following
operations:
1. On all read operations and all write append operations, the recorded density is the
density to be used.
2. On a Write from BOT, the tape density may be changed by:
•
The Density Select button. Using the Density Select button always
overrides a host selection.
•
A programmable host selection via your operating system. (The Density
Override light is off, indicating automatic or host density selection.)
••••
Native default density 10.0 and Compress (assuming the Density Select
button or the host selection was not used.)
How to Select Density
To select density with the DLT2000:
1. Load the tape in the drive. The yellow Tape in Use light blinks while the tape loads
and calibrates.
2. After calibration completes, Tape in Use remains lit.
3. The light shows the tape's prerecorded density, such as 2.6 or 6.0.
