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.
