*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

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.
