一种数据记录装置构成部分为：一个输入单元，用于接收其中扇区大小的比率不等于整数比率的第一和第二数字数据；一个字组分段单元，用于当假定第一数据的扇区大小设为A和第二数据的扇区大小设为B时插入第一数据nA和第二数据mB(n和m为2或大于2的整数且n≠m)并且用于形成字组结构数据；一个记录处理单元，用于对字组结构数据执行纠错编码和数字调制；和一个记录单元，用于将记录处理单元输出的记录数据记录到数据记录介质。 A data recording apparatus is constructed by: an input unit (1, 2, 4) for receiving first and second digital data in which a ratio of sector sizes is not equal to an integer ratio; a block segmenting unit (7) for inserting first data nA and second data mB (n and m are integers of 2 or more and n NOTEQUAL m) when it is assumed that a sector size of first data is set to A and a sector size of second data is set to B and for forming data of a block structure; a recording processing unit (8) for performing an error correction encoding and a digital modulation to the data of the block structure; and a recording unit (9, 10) for recording the recording data from the recording processing unit (8) to a data recording medium (3) .
