ABSTRACT:
A bias current measuring unit measures a drive current which is supplied to a VCM when a carriage is moved to a plurality of measurement positions and held as a bias current to remove a mechanical offset that is applied to the carriage and stores into a storing unit. A bias current operating unit obtains a corresponding bias current Vd with reference to the storing unit on the basis of a carriage position during a seeking operation and adds the bias current Vd to a seek current Vs which is supplied to the VCM, and removes a disturbance component which is caused by a mechanical offset due to a friction between a bearing and a rail, a tension by an FPC, and the like.
