Abstract:
    This invention discloses a method for coding and decoding data, namely carries out limited code and decode of high code rate running length in data storage and communication environment including: dividing sub-blocks to input data, testing if the sub-block values are conflicted and carrying out no-conflict mapping based on the test value or the mark sub-blocks outputting data to instruct sequence numbers of the conflicted sub-blocks and present the array rule of the mark sub-blocks, the non-conflicted sub-blocks of the rest input data give the content values to vacant output sub-blocks and adding 10 to special states. This invention designs a code and a decode method of limited running length with the code rate of 32/33(d=0, k=6) and designs a code word mapping method of a running length limitation with the code rate of 128/129(d=0, k=14) combining the cross interposition skill.
