Paragraph Number

131

In some embodiments, using a balanced code as the secondary/inner error correcting code results in a balanced ECC chunk. In certain embodiments, however, the DC balance module 404 may determine that a read ECC chunk encoded has become unbalanced, or does not exhibit an expected ratio of binary ones and binary zeroes, due to errors or the like. In one embodiment, the adjustment module 306 may adjust one or more media parameters based on error information from the DC balance module 404, to restore the balance of the at least one ECC chunk.
