PROBLEM TO BE SOLVED: To provide an error correcting method significantly improving the recording density of a recording medium, in which Reed-Solomon product codes, which are currently used for DVD, are optimally used to significantly improve burst error correcting ability. SOLUTION: An outer code is generated for each column and an inner code is generated in units of rows, separately for even-numbered rows and odd-numbered rows of a data block composed of data sectors. The outer codes are distributed and interleaved for each sector of the data block. Also, data processing can be performed while maintaining a sector ID, so that data processing can be easily performed. COPYRIGHT: (C)2008,JPO&INPIT
