    • The present invention relates to method and apparatus of converting a series of data words into modulated signals. This method generates for each data word a number of intermediate sequences by combining mutually different digital words with that data word, scrambles these intermediate sequences to form alternative sequences, translates each alternative sequence into a (d,k) constrained sequence, measures for each (d,k) constrained sequence not only an inclusion rate of undesired sub-sequence but also a running DSV (Digital Sum Value), and selects one (d,k) constrained sequence having 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. According to the present invention, efficient DSV control can be achieved for even relatively-long sequences.
    • 本发明涉及将一系列数据字转换为调制信号的方法和装置。 该方法通过将相互不同的数字字与该数据字组合来为每个数据字生成多个中间序列,对这些中间序列进行加扰以形成替代序列,将每个备选序列转换为(d,k)约束序列, d,k)约束序列不仅是不期望的子序列的包含率,而且是运行的DSV(数字和值),并且选择具有小的包含率的一个(d,k)约束序列用于在光学或磁光学上记录 (d,k)约束序列中的记录介质,其运行DSV的最大值小于预设限制。 根据本发明,对于甚至相当长的序列,可以实现有效的DSV控制。
