ABSTRACT:
A method and apparatus of converting a series of data words into modulated signals generates for each data words, a number of intermediate sequences by combining mutually different digital words with a data word, scrambles the intermediate sequences to form alternative sequences, translates each alternataive sequence into a (d,k) constrained sequences, measures for each (d,k) constrained sequences, not only an inclusion rate of an undesired sub-sequence but also a running DSV (Digital Sum Value), and selects one (d,k) constrained sequence having a small inclusion rate for recording on an optical or magneto-optical recording medium among the (d,k) constrained sequences having maximum value of running DSV, smaller than a preset limit. Accordingly, efficient DSV control can be achieved for even relatively-long sequences.
