Methods and devices for encoding data symbols in accordance with a BCH code to obtain a code word in which parity symbols are located in the middle of the code word. The data symbols are supplied to a parity determining device in a predetermined order to produce the parity symbols, which parity determining device either employs a shift register or a shift register bank. When the parity determining device employs a shift register, depending upon the predetermined order in which the data symbols are supplied to the shift register, the data symbols are either (a) forward shifted through the shift register, after each data symbol has been initially modified on the basis of previously supplied data symbols, and further modified as each is being shifted through the shift register on the basis of subsequently received data symbols so as to produce the parity symbols or (b) forward shifted through the shift register, after each data symbol has been modified on the basis of previously supplied data symbols, so as to produce provisional parity symbols which are, in turn, backward shifted through the shift register to produce the parity symbols. Once the parity symbols have been produced, they are positioned among the data symbols so as to produce the code word.
