ABSTRACT:
The disclosed technology provides systems and methods for encoding data based on a run-length-limited code and an error correction code to provide codewords. The codewords include RLL-encoded data that are produced based on the RLL code, and parity information that are produced based on the error correction code. The parity information is interleaved among the RLL-encoded data. In one embodiment, the codeword is produced by separately producing the RLL-encoded data and the parity information, and interleaving the parity information among the RLL-encoded data. In one embodiment, the codeword is produced by producing the RLL-encoded data, and using erasure decoding to compute the parity information.
