ABSTRACT:
An error correction processor is disclosed for correcting errors in binary data read from a disk storage medium, wherein the binary data comprises a first and second set of intersecting ECC codewords of a multi-dimensional codeword. The error correction processor comprises a data buffer for storing the ECC codewords read from the disk storage medium; a syndrome generator for generating ECC syndromes in response to a codeword in the second set; an error-locator polynomial generator for generating an error locator polynomial .sigma.(x) in response to the ECC syndromes; a selector for selecting between the error-locator polynomial .sigma.(x) and an erasure polynomial .sigma.(x).sub.EP, wherein:
