<P>PROBLEM TO BE SOLVED: To record visible information in a thermosensitive plane of an optical disk in addition to information recording for a recording plane without providing individually a new apparatus or the like. <P>SOLUTION: When recording data is supplied from a host PC 110, the recording data is supplied to a laser driver 19 through a buffer memory 36, an encoder 17, and a strategy circuit 18, an optical disk D is irradiated with a laser beam in accordance with the recording data, and information is recorded. On the other hand, 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 part 16, a FIFO memory 34, and a drive pulse generating part 35, a laser beam corresponding to the picture data is irradiated, and a visible picture is formed on the thermosensitive plane of the optical disk D. <P>COPYRIGHT: (C)2008,JPO&INPIT |
