    • An apparatus, and related method, for recording data that includes a controller to generate control information required to record a main data. The control information including at least one information unit for a specific writing speed and recording layer. The information unit includes write strategy parameters for first write strategy type to be used for the writing speed and recording layer, the first write strategy type being one of an (n−1) write strategy type and an n/2 write strategy type, where n is a length of mark and each type represents a number of write pulse to form a corresponding mark. A writing/reading unit records the control information at a specific area of a recording medium, wherein the controller controls the writing/reading unit to record the control information and to record the main data on the recording layer using write strategy parameters for the first write strategy type included in the information unit, at the specific writing speed.
    • 一种用于记录包括控制器的数据的装置和相关方法,用于生成记录主数据所需的控制信息。 所述控制信息包括用于特定写入速度和记录层的至少一个信息单元。 信息单元包括用于写速度和记录层的第一写策略类型的写策略参数,第一写策略类型是(n-1)写策略类型和n / 2写策略类型之一,其中 n是标记的长度,并且每个类型表示形成对应标记的写入脉冲的数量。 写/读单元将控制信息记录在记录介质的特定区域,其中控制器控制写/读单元记录控制信息,并使用写入策略参数将记录层上的主数据记录在记录层上 策略类型包含在信息单元中,具体写入速度。

    • A method and apparatus of converting a series of data words into modulated signals generates for each data word, a number of intermediate sequences by combining mutually different digital words with that data word, scrambles the 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. Accordingly, efficient DSV control can be achieved for even relatively-long sequences.
    • 将一系列数据字转换为调制信号的方法和装置通过将相互不同的数字字与该数据字相结合,为每个数据字产生多个中间序列,对中间序列进行加扰以形成替代序列,将每个替代序列转换成 (d,k)约束序列,每个(d,k)约束序列的测量,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),并且选择一个(d,k)约束 在具有最大运行DSV值的(d,k)约束序列中,在光学或磁光记录介质上记录的包含率小的序列。 小于预设限制。 因此,对于甚至相对较长的序列,可以实现有效的DSV控制。
