| 1. A data encoding method for error correction, comprising:
arranging recorded data into a plurality of M×N data blocks, wherein M is the number of row, and N is the number of column;
adding a Check Sum on Row (CSR) of P bytes for each row of each M×N data blocks, and adding a Check Sum on Column (CSC) of
Q bytes for each column of each M×N data blocks, thereby forming a (M+Q)×(N+P) Error Correction Code (ECC) block;
arranging K times (M+Q)×(N+P) ECC blocks into one (M+Q)×(K(N+P)) ECC block, wherein K is a positive integer greater and equal
than 1;
dividing the (M+Q)×(K(N+P)) ECC block into a plurality of data sectors, wherein each data sector is formed in a unit of L
rows and a sector address information with a length of L bytes is added in front of each data sector; and
rearranging each data sector with the sector address information into a (M+Q)×(K(N+P)+1) data recording block.
