ABSTRACT:
First and second synchronous words having respective numbers of times of inversion different from each other in NRZI conversion are generated in a synchronous word generation portion, and first and second code word series data are generated by arranging code word data generated making reference to a run-length coding table after these two synchronous words. With respect to the first and second code word series data, DSV calculation results stored in two DSV calculation peak value memories corresponding to these data are compared with each other by a peak value comparison portion. Based on a comparison result, the code word series data having a smaller direct-current component generated in NRZI conversion is selected.
