    • A method and apparatus are provided for encoding successive data words into respective code words. Each data word is mapped into data segments that are constrained to a first number of bit patterns, which is less than a second number of bit patterns that satisfy a first constraint. The data segments are encoded into intermediate code word segments selected from a first set of the bit patterns that satisfy the first constraint, wherein at least some of the bit patterns in the first set violate a second constraint. The intermediate code word segments are encoded into respective code word segments by encoding the intermediate code word segments that violate the second constraint with code word segments selected from a second, different set of the bit patterns that satisfy the first constraint and the second constraint.
    • 提供了一种用于将连续数据字编码成相应代码字的方法和装置。 每个数据字被映射到被限制到第一数量的位模式的数据段,其小于满足第一约束的第二数量的位模式。 数据段被编码成从满足第一约束的第一组位模式中选择的中间码字段,其中第一组中的至少一些位模式违反第二约束。 通过对从第二不同的满足第一约束和第二约束的位模式的集合中选择的码字段编码违反第二约束的中间码字段,中间码字段被编码成相应的码字段。
