Data coding method capable of correcting error

The invention discloses a correct data coding method, error correcting code is added into data which is to be stored before data is written to recording memory medium, it includes row checking code and line checking code, a error correcting code block is formed, then at least one error correcting code blocks forms a data matrix to resist longer data continuous errors. At last the data matrix is incised into sections, separate section address information are added aiming at every section, the coding program has accomplished, according to method of the invention, section address information will not be added into the coding range of error correcting code, so the error detecting capacity of main data block improved greatly, besides, the invention provides three coding block formats, which form is chosen to write into the recording memory medium to make data storing more elastic based on the situation needed.
