*1 Maximum current 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.
