Abstract

An apparatus for processing data includes a storage medium operable to store encoded data, and a read channel circuit with a low density parity check encoder operable to encode data to generate the encoded data, and a low density parity check decoder operable to decode the encoded data retrieved from the storage medium. The read channel circuit is operable to perform a column rotation on the encoded data prior to storage and after retrieval before decoding.
