PROBLEM TO BE SOLVED: To provide a storage device which appiies a bias current measured at an appropriate timing after positioning, at an appropriate timing after completion of positioning. SOLUTION: This storage device drives an actuator with a head by a drive section and performs seeking and positioning of the head to a target track of the storage medium. 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 counting an elapse of the waiting time. The bias current applying unit reads the bias current value from the storage unit and applying the bias current to the driving unit after the elapse of the waiting time. COPYRIGHT: (C)2009,JPO&INPIT
