Abstract
In the storage device, a buffer memory stores a command queue consisting of a plurality of commands received from a host. A control section searches a command to be executed next to a command which is being executed from the command queue according to a predetermined condition, and then performs rearrangement of the commands in the command queue such that. The predetermined condition is that, the time required to move the head, which head performs reading/writing on the magnetic disk, to the magnetic disk after the execution of the command which is being executed is finished is not longer than a predetermined time.
