Claim 3:
4. The magnetic disk device of claim 1, further comprising:
an aging time determination unit determining whether an unexecuted second exceeding command that exceeds the aging time remains in the command queue,
wherein
the command selection processing unit selects a command to be executed by considering the latency limit time when determining that the second exceeding command does not remain in the command queue, or selects the second exceeding command as a command to be next executed without considering the latency limit time when determining that the second exceeding command remains in the command queue,
the aging time is applied uniformly to all commands in all queues stored in the command queue, and
each of the plurality of latency limit times of the latency limit time determination table is shorter than the aging time.
