A storage device includes a storage unit, a timer unit and a bias current applying unit. The storage unit stores, in advance, a value of a waiting time until application of a bias current to the driving unit to eliminate an external force applied to an actuator after completion of positioning, and a value of a bias current to be applied to the driving unit after the elapse of the waiting time, in association with a track position. The timer unit reads the waiting time from the storage unit and counts an elapse of the waiting time. The bias current applying unit reads the bias current value from the storage unit and applies the bias current to the driving unit after the elapse of the waiting time.
