Current and Power
Requirements 1
The tape drive draws the highest current (and power) during the native
write modes.
Standby is measured with the tape loaded and tensioned or
untensioned, and
Idle is measured with power on with no tape loaded.
(The power drawn in these two modes is similar enough that they are
listed together.)
