    • PROBLEM TO BE SOLVED: To efficiently process a command coming from a host. SOLUTION: The command coming from the host is stored, and when the command is next executed, the command shortest in the time a head takes to reach an access start position is selected and the priority command to be preferentially executed is detected. Each stored command excluding the running command and the priority command, is searched in the ascending to find order of end angles with respect to the end angle of the running command ascending to find the first command that the disk head moves, even if the search is executed before the priority command, before the arrival time of the disk head to the access start position of the priority command when the priority command is decided to be executed next. The first command having the smallest end angle is decided as the command to be executed next on the basis of the minimum waiting among the found first commands and the end angle of the running command.
