5.5 Selecting Density
Section 5.5 describes the loader's density select feature.
_________________________ Caution __________________________
If a prerecorded tape and write from beginning of tape (BOT),
all prerecorded data is lost. This includes density changes,
since they only occur when writing from BOT.
___________________________________________________________
Ways of Selecting Density
Density selection is only available when you use a CompacTape III tape..
The user can select CompacTape III tape density by using any of the following:
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 GB for the CompacTape III (assuming the
Density Select button or the host selection was not used).
How to Select Density
To select density with the DLT2700 using the CompacTape III cartridge:
1. Press the Load/Unload button to load the cartridge into the drive. The yellow Tape
in Use light blinks while the tape loads and calibrates.
2. After calibration completes, the yellow Tape in Use light remains lit.
3. The indicator shows the tape's prerecorded density lights, such as 2.6, 6.0 or 10.0.
4. The user can use the loader operator control panel at various times, not just after
loading a tape. Density selection is inactive until the write from BOT command is
issued. The controller remembers the density selection state until you do one of the
following:
•
Change the density selection
•
Eject the magazine from the loader
