ABSTRACT:
A method and apparatus are provided for storing data. The method and apparatus generate a plurality of ECC codewords, which define a cooperative block. Each ECC codeword includes a plurality of information symbols and first and second sets of corresponding redundancy symbols. Shared redundancy symbols are generated for the cooperative block based on a combination of the second sets of redundancy symbols from the plurality of ECC codewords. A respective set of parity codewords is generated for the cooperative block based on the shared redundancy symbols. The second set of redundancy symbols for each ECC codeword in the cooperative block is derivable from the parity codewords. The cooperative block and the respective parity codewords are stored, without the second set of redundancy symbols, on a storage medium.
