Encoding/decoding method and apparatus and disk storage device
An encoding/decoding apparatus generates data sequences with first and second interleave structures by respectively performing data on a data sequence to be encoded, interleaving processes based on different first and second data interleaving schemes, generates sequences of first and second error correcting codes respectively corresponding to the data sequences with the first and second interleave structures, and generates an encoded data sequence which has the generated sequences of first and second error correcting codes affixed to the data sequence to be encoded. The encoding/decoding apparatus decodes a data sequence to be decoded, included in the encoded data sequence, by using the data interleaving processes and the sequences of first and second error correcting codes.
