Energy
Efficiency (*4)
*1
Maximum current and power at starting spindle motor.
*2
Current and power level when the operation (command) that accompanies a
transfer of 63 sectors is executed 3 times in 100 ms
*3
Power requirements reflect typical values for +5 V power.
*4
Energy efficiency based on the Law concerning the Rational Use of Energy
indicates the value obtained by dividing power consumption by the storage
capacity. (Japan only)
*5
The seek average current is specified based on three operations per 100
msec.
*6
IPM mode: Slumber mode.
