*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.
