<P>PROBLEM TO BE SOLVED: To record visible information onto a label face of an optical disk without preparing a new device individually. <P>SOLUTION: Record data is supplied from a host PC 110, the record data is supplied to a laser driver 19 through a buffer memory 36, an encoder 17, and a strategy circuit 18, an optical disk 200 is irradiated with a laser beam in accordance with the record data, and information is recorded on a recoding layer of the optical disk 200. When picture data is supplied from the host PC 110, the picture data is supplied to the laser driver 19 through the buffer memory 36, a control section 16, a FIFO memory 34, and a drive pulse generating section 35, laser beam irradiation corresponding to the picture data is performed, and a visible picture is formed on a color change layer 205 of the optical disk 200. <P>COPYRIGHT: (C)2004,JPO |
