Abstract
A data storage device is disclosed comprising a storage medium. First data is encoded into a first codeword, and second data is encoded into a second codeword, wherein a first code rate of the first codeword is less than a second code rate of the second codeword. The first codeword and the second codeword are interleaved to generate an interleaved codeword that is written to the storage medium.
