1. On a write from beginning of tape (BOT), tape density is selected by one of the
following:
•
Front panel Density Select mode
__________________________NOTE ____________________________
The user can execute a front panel density selection at any time, but the
selection takes effect only on the next write from BOT.
____________________________________________________________
•
Programmable host selection via your operating system
•
Native default density 10 GB and Compress (assuming you did not use
the Select mode or the host selection)
2. On all read operations and all write append operations, the recorded density is the
density to be used.
__________________________CAUTION _________________________
Doing any write from BOT destroys existing data on tape.
