Abstract Example channel circuits, data storage devices, and methods for using an adjustable code rate based on an extendable parity code matrix are described. Data units may be read from a storage medium. Multiple sets of parity bits may be available for different data units, different sets of parity bits having a different number of parity bits corresponding to different parity matrices and desired code rates. A primary parity matrix may provide a base code rate and one or more extended parity matrices may provide increased code rates based on additional rows for increased decoding. Error correction code (ECC) decoding may be selectively performed based on the different sets of parity bits and corresponding parity matrices, resulting in the output of a decoded data units based on the data units from the read signal.
