<P>PROBLEM TO BE SOLVED: To provide an optical disk recording device capable of suppressing an increase in the number of channels of a transmission line. <P>SOLUTION: The optical disk recording device includes a record pulse information generation part 11 for generating record pulse information corresponding to a power level of a laser beam from a recording signal, a recording code generation part 12 for generating a recording code obtained by coding the record pulse information, a transmission line 2 for transmitting the recording code, and a decoding code generation part 33 for decoding the recording code. The recording code generation part 12 generates the recording code on the basis of a circulation code in which each transition of the power level is expressed by using a Gray code. The decoding code generation part 33 decodes the recording code by using a recording code corresponding to a power level at a specific timing and a recording code corresponding to a power level immediately before the power level at the specific timing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
