According to one embodiment, a memory of a magnetic disk device includes a plurality of control queues respectively corresponding to a plurality of actuator systems. A controller receives a plurality of first commands from a host, and stores the plurality of first commands in one of the plurality of control queues. The controller generates a second command for internal processing, and stores the second command in a first control queue that stores a smallest number of commands among the plurality of control queues. The controller executes, for each of the plurality of control queues, processing one or more commands stored in one control queue of the plurality of control queues by using an actuator system corresponding to the one control queue among the plurality of actuator systems.
