(note 6) Motor is not rotating and heads are unloaded on the ramp.
7.3 Energy Consumption Efficiency
Energy consumption efficiency (W/GB) Classification
Power consumption at Low power idle / Capacity
MK3006GAL 0.010 D
MK4006GAH 0.0075 E
MK6006GAH 0.005 E
Energy consumption efficiency is calculated in accordance with the law regarding efficiency of energy
consumption
:Energy saving law,1979 law number 49.
Calculation of Energy consumption is dividing consumed energy by the capacity.
The consumed energy and capacity shall be measured and specified by the Energy saving low.
