摘要： A recording/playback apparatus includes an upper control unit which transmits a composite command, which includes a real processing command and a virtual command, to a disk device. The disk device performs a process until a point of time when an operation cannot be continued unless the virtual command is changed to the real processing command to be operated beforehand. Instead of standing by after the real processing command is completed, the disk device can voluntarily operate beforehand in response to the virtual command, while selecting an optimum seek speed or disk rotation speed. The recording/playback apparatus can thus maintain the continuity of continuous data and perform an optimum operation in accordance with an expected performance while switching speeds of seek and disk rotation in detail.
