In a disk storage a command controller issues a seek command and transmits it to a seek command manager. A head position controller performs a seek operation. If the head position controller is not busy with the seek operation, the seek command manager transmits the seek command to the head position controller. If the head position controller is busy with the seek operation, the seek command manager queues the seek command in a memory and transmits the seek command to the head position controller after the head position controller has finished the seek operation.
