Errors in parallel binary data produced by a plurality of data track, e.g., a plurality of parallel shift registers, are corrected by a system in which the shift registers which are stuck, i.e., inalterable, are determined and counted. By single Hamming error detection means, the presence of a Hamming error and an indication of the bit position of a single Hamming error is made. Comparison means determine if the indicated Hamming error is coincident with a stuck track. Then, dependent on the parity condition of the data as well as the count of stuck tracks, apparatus is provided for complementing one or more of the stuck tracks and/or correcting the indicated Hamming error.
