3.2.3 Current and Power Requirements
lists the current and power requirements for both versions
of the tape system (internal and tabletop). The tabletop version requires AC power.
The highest current (and power) is drawn during the native write modes and
backward-read compatibility (BRC) read modes, so they are outlined in
backward-read compatibility (BRC) read modes, so they are outlined in
. 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.)
Power-up current surges are less than those encountered during motor
accelerations, and so are not listed separately.
