<P>PROBLEM TO BE SOLVED: To provide a disk device capable of reducing power consumption. <P>SOLUTION: The disk device 10 adopts two kinds of recording media which are a magneto-optical disk 12 and a memory card 14 as the recording media and data are copied to each other between the magneto-optical disk 12 and the memory card 14. At the time, matched with the access speed Vc of the memory card 14, the access speed Vd of the magneto-optical disk 12, that is the rotation number R of a spindle motor 16, is set. Also, matched with the rotation number R of the spindle motor 16, the power α or β of a laser beam 42 emitted from an optical pickup 40 is set as well. <P>COPYRIGHT: (C)2004,JPO |
